At West Wemyss, Carboniferous coal seams and plant-bearing shale can be seen along the shore east of the harbour. The Scottish Middle Coal Measures Formation records rivers, lakes and wetland forests, while redistributed mining spoil adds a different source of loose rock. Visit for geological observation and photography; collecting is not recommended while a reported refusal of permission remains unresolved.
FIND FREQUENCY: ♦♦♦♦♦ – Plant remains were commonly recorded in the shale; this is an observation guide, not an assurance of collecting permission.
CHILDREN: Close supervision is essential. Use only safe established paths and keep well away from cliffs and the water’s edge.
ACCESS: ♦♦♦ – A walk from the village and harbour along the coastal route; conditions depend on tides, weather and erosion.
TYPE: Coal Measures bedrock, plant-bearing shale and mixed industrial material on the foreshore.
DIRECTIONS
♦ West Wemyss lies northeast of Kirkcaldy. Follow the A955 towards Buckhaven and take the signed road to West Wemyss near Coaltown of Wemyss.
♦ Descend into the village on the approach historically labelled “West Wemyss Toll” on maps. Use lawful marked village or harbour parking, following current signs and leaving entrances clear.
♦ Use the harbour for orientation, then follow the established route east along the embankment towards the cliffs and the next bay. Keep to a safe route and turn back if the shore or path is affected by tide, erosion or fallen material.

FOSSIL HUNTING
The characteristic fossils here are plant impressions, stems, leaves and fragments of trunk preserved in shale. The original observations describe fossil-rich pockets rather than a uniformly fossiliferous layer: a seemingly plain surface may be followed by a patch crowded with overlapping plant debris. From safe positions, examine naturally exposed bedding surfaces and photograph any recognisable material where it lies. The layered cliffs near the harbour are useful for seeing the relationship between dark coal seams and the intervening sedimentary beds, but are not a place to approach or work beneath.
On a shale surface, look first for a repeated biological pattern. Leaf or frond impressions can appear as branching outlines or rows of leaflets, sometimes with fine veins; stem fragments may be straight or curved, with ribbing or repeated markings. A dark carbonaceous film can preserve the outline of a plant with very little relief, whereas a cast or impression records its shape in the rock. Lighting from a low angle often makes these differences easier to photograph. Cracks, mineral stains and irregular weathering marks are not sufficient evidence for a plant identification.
Trunk fragments were also reported among the foreshore material. Regular surface ornament may be useful, but a weathered ribbed fragment is not enough to establish a genus: the arrangement of scars, branching, nodes and any attached leaves matters. Photograph an overall view and close-ups with a scale, without moving or scraping the surface. The existing fossil photographs below record the historical material; their camera-file labels do not identify the plants to species.
Bivalves have been reported as well as plants. A shell outline, hinge region and growth lines can help distinguish a bivalve impression from an isolated leaf, although broken or flattened material may remain uncertain. Coal Measures lakes supported nonmarine bivalves, while separate marine incursions left marine bands. A shell-bearing block cannot be called a marine-band specimen simply because it contains shells. No securely verified species inventory or bed assignment is available for this short harbour walk.
Farther along the bay, the original account describes jumbled mining waste mixed with bricks and other artificial debris. This material differs from an undisturbed bed: loose shale and other blocks can have been transported from different seams and redistributed along the coast. Record whether a fossil is in continuous bedrock, a fallen block, or mixed beach material; do not assign a loose specimen to the cliff behind it. A wide contextual photograph can be as valuable as a close-up.
Leave fossils and rock in place. A previous refusal of collecting permission has been reported, so this guide does not recommend shale splitting, cliff work or taking blocks home. If a fossil appears unusual or scientifically important, record its position and seek specialist advice rather than exposing more of it.

1982 – Local rocks and fossils booklet
The West Wemyss Environmental Education Centre published Rocks and fossils of West Wemyss, an illustrated 28-page booklet. Its publication records an established local educational interest in the shore’s rocks and fossils; it does not establish a particular fossil discovery or species record.
1999 – Mining subsidence and coastal change studied
Elisabeth Saiu completed doctoral research on the effects of mining subsidence along the southeast Fife coast, including the West Wemyss area. The work placed changes to this shore within the interaction between underground mining and coastal processes.
1999 – Coastal stratigraphic framework explained
M. A. E. Browne and D. G. Woodhall’s Kirkcaldy map explanation set out the geological framework for the district. It distinguished the Lower Coal Measures coast west of West Wemyss from the Middle Coal Measures succession continuing towards Buckhaven, providing context for interpreting the local exposures.
2003 – Subsidence modelling related to erosion
W. S. McLean and M. A. E. Browne modelled mining subsidence around the Wemyss villages and discussed its contribution to coastal erosion, alongside the changing supply of colliery spoil. This helped explain why the modern shoreline cannot be understood from the bedrock alone; it was not a present-day cliff-stability assessment.
GEOLOGY
The bedrock coast at West Wemyss exposes part of the Scottish Middle Coal Measures Formation, within the Scottish Coal Measures Group. These are Late Carboniferous, or Pennsylvanian, rocks of Duckmantian age, traditionally called Westphalian B. The geological story is chiefly one of low-lying river and delta plains, shallow lakes and wetland forests. Dark coal seams and finer-grained shale contrast with more resistant beds, allowing the layered character of the succession to be appreciated from a safe distance.
Rivers carried sand into channels and deltas, while silt and mud settled in quieter water or accumulated on floodplains. Some sedimentary cycles become coarser upwards as a delta advances into a lake; others fine upwards as a river channel fills. Rooted mudstone and siltstone record soils, and coal developed from accumulated organic matter in wet environments. The resulting alternation of sandstone, siltstone, mudstone, seatearth and coal explains why different beds weather differently and why plant debris is especially conspicuous on some fine-grained surfaces.
The environment was not permanently freshwater. Occasional marine transgressions interrupted the predominantly nonmarine succession and produced marine bands that are important for correlation across the coalfield. Nonmarine shell bands represent a different setting. These distinctions matter when interpreting a fossil, but individual seams and marine bands cannot reliably be named from their colour or position in a photograph. The harbour cliffs have not been matched here to a complete measured bed-by-bed log.
The modern shore also contains industrial deposits. Mining waste, artificial debris and eroded material have been mixed and moved by the sea, so an apparently geological cliff or loose block need not be undisturbed local bedrock. Regional work identifies redistribution of Wellesley spoil towards the Wemyss villages; it would be misleading to attribute every block solely to Michael Colliery. The original guide’s distinction between layered bedrock and jumbled spoil remains particularly useful.
Mining beneath the coast and the later reduction in spoil supply both contributed to coastal change. The 2003 subsidence study provides a regional explanation, with modelling uncertainties, rather than a forecast for an individual cliff today. To the west, towards Dysart, the coastal succession includes the Scottish Lower Coal Measures Formation. That western approach is distinct from the east-of-harbour exposures described by this guide, and the fuller district seam sequence below is context rather than a walking-route log.
Detailed geology, depositional environments and the regional seam framework around West Wemyss.
This account separates the shore east of West Wemyss harbour from the broader Fife coalfield succession. The formal formation framework is secure, but no continuous measured section or verified member subdivision has been established for this short visit. Named district seams below are correlation context, not instructions for locating a bed beside the harbour.
SCOTTISH COAL MEASURES GROUP
The group contains repeated coal-bearing sandstone, siltstone, mudstone and soil horizons. Its Lower, Middle and Upper formations are distinguished using regional marker horizons and fossil correlations, not by assuming every visible change of rock type represents a formation boundary. Older accounts use Upper Carboniferous, Silesian and Westphalian terminology; Duckmantian corresponds to Westphalian B in the terminology used here.
Scottish Middle Coal Measures Formation
Age, extent and thickness. The formation is Duckmantian and includes the coastal reference exposures between West Wemyss and Buckhaven. Its approximately 350 m maximum is based on broader Fife coastal evidence and the dip-corrected Sealab No. 1A borehole offshore. It is not a measurement of the harbour cliffs or the thickness visible on this walk.
Lower boundary: Queenslie (Vanderbeckei) Marine Band. The formation begins at the base of this marine band, or its local equivalent, above the Scottish Lower Coal Measures. Where the horizon cannot be recognised, the formal scheme uses the closest approximation from nonmarine bivalve faunas. The band records a marine incursion; its precise exposure has not been established at the guide’s shore reference.
Sandstone, siltstone and mudstone cycles. Thick sandstone bodies in the formation represent river and delta-distributary channels. Upward-coarsening sequences record delta advance, whereas channel deposits can fine upwards. Mudstones with nonmarine faunas accumulated in shallow lakes; plant-bearing and rooted siltstones and mudstones include floodplain deposits. These are recurring facies, not separately named members or a fixed sandstone-to-coal stack repeated identically everywhere.
Seatearth and coal. Rooted beds record former soil surfaces beneath or associated with wetland vegetation; coal records organic accumulation. Thin fossil-bearing shale surfaces and plant debris need not belong to the coal seam itself. The original guide also reports resistant ironstone blocks, but a distant photograph does not justify identifying every pale resistant band as limestone.
Nonmarine shell horizons and marine interruptions. The formation’s regional bivalve scheme includes the upper Modiolaris and lower Similis-Pulchra chronozones, with Anthracosia an important genus. The regional account also assigns it to the NJ miospore zone. These are tools for correlating sampled successions, not identifications of the photographed West Wemyss fossils. Marine bands interrupt the fluviodeltaic deposits; a shell in an unprovenanced block does not determine which environment or band it came from.
Upper boundary: Aegiranum (Skipsey’s) Marine Band. The top is the base of this band, which also defines the base of the Scottish Upper Coal Measures. In the Kirkcaldy district correlation the equivalent marker is labelled the Buckhaven Planolites Band. The older attribution of the Chemiss Den Marine Band to Skipsey’s is not the accepted correlation used here.
Regional named-horizon context: how to read the following account. The Frances–Seafield column in the 1999 Kirkcaldy explanation links named coal seams, marine bands and nonmarine shell horizons across the district. The order below runs from older to younger within each stated interval. It is not a measured West Wemyss harbour column, and no seam thickness, fossil assemblage or exact shore position should be inferred where none is given. Paired Den and Coxtool seams remain pairs, not members.
Scottish Lower Coal Measures Formation — western approach and regional context
The published coastal framework places Lower Coal Measures between Dysart Harbour and West Wemyss. It describes Langsettian strata, with the RA miospore zone, chiefly lacustrine and fluviodeltaic sandstone, siltstone and mudstone. Coal and seatearth occur within upward-coarsening or upward-fining cycles, with minor cannel, blackband and clayband ironstone and nonmarine shell-rich “mussel bands”. These formation-wide details concern the western coast and district, not a newly measured section east of this harbour.
Lower Dysart and Dysart Lingula Band. The local base of the Lower Coal Measures is taken at the Lower Dysart Coal. The Dysart Lingula Band lies immediately above it in the regional column and is distinguished by its brachiopod record; its name does not identify a band in the visitor photographs.
Coronation and Dysart Main. These named coal seams occur above the Dysart Lingula Band, with Coronation below Dysart Main in the regional correlation. Their exact thickness and present exposure on this visit are not established.
Dysart Musselband and Victory. The Dysart Musselband lies above Dysart Main and is shown with nonmarine bivalves. Victory is the next named coal above it in the column. A fossil-bearing loose block cannot be assigned to either horizon on this order alone.
Sandwell, Boreland and More. These named seams follow Victory upwards in that order. The regional figure marks nonmarine bivalves near the Boreland and More levels, but supplies no species identification for the guide’s beach material.
Branxton, Bowhouse and Earl David’s Parrot. These coal names follow More upwards. They belong to the district’s mining and correlation framework; none is treated here as a verified named outcrop on the harbour walk.
Frances Wood and Wemyss Parrot. Frances Wood is followed upwards by Wemyss Parrot, below the Queenslie Marine Band. That band, rather than the name of either coal, marks the formal transition into the Middle Coal Measures.
Scottish Middle Coal Measures Formation — regional named-horizon continuation
Middle Coal Measures district horizons above Queenslie. The following continue the regional column upwards; they do not add a second local formation or claim a continuous exposure.
Frances Extra and Bush. Frances Extra is shown just above the Queenslie boundary horizon, followed by Bush. They are useful names when consulting mine records or the regional correlation, without a measured thickness or exposure assignment here.
Chemiss. The Chemiss Coal lies above Bush and below the Den seams. The Kirkcaldy explanation records a regional thickness from 1.5 m to more than 4 m and extensive working; it was known as the Number Two Mine Coal in the Westfield basin. Those measurements and the mining alias are regional context, not a harbour-bed measurement.
Upper and Lower Den; Upper and Lower Coxtool. The paired Den seams overlie Chemiss and are followed by the paired Coxtool seams. The diagram preserves their splitting and correlation as paired coals. Their names do not establish formal members, and no individual thickness is transferred to the shore.
Barncraig Under and Barncraig. Barncraig Under lies below Barncraig. The district account describes the mudstone roof of Barncraig as usually rich in nonmarine bivalves. This is useful environmental context, but does not identify a particular shell photograph or a loose beach block as Barncraig material.
Wall and Pilkembare. Wall and then Pilkembare follow Barncraig upwards. The Wall mudstone roof is also usually rich in nonmarine bivalves in the district. Seams above Barncraig are generally less than 1.4 m thick and can be absent locally, illustrating why a complete regular stack cannot be assumed at every exposure.
Wellesley Marine Band and Chemiss Den Marine Band. Both lie below Lyon, with Wellesley below Chemiss Den in the regional column. They mark marine influence within the Middle Coal Measures. Chemiss Den was formerly correlated with the Aegiranum (Skipsey’s) Marine Band; the later framework separates it from that higher formation-boundary horizon.
Lyon. Lyon is the named coal above these marine bands. The continuation of the regional column places it below the Buckhaven Planolites Band; this order does not establish a locally visible Lyon seam.
Scottish Upper Coal Measures Formation — younger regional context
Younger regional continuation: Buckhaven Planolites Band and Methil Dock Musselband. The Buckhaven Planolites Band is the Aegiranum boundary marker at the base of the Scottish Upper Coal Measures. The district account describes reddened mudstone with foraminifera and bivalves at this level. Methil Dock Musselband is shown higher in the regional column. These younger horizons belong to the wider continuation towards Buckhaven and Methil, not to an asserted Upper Coal Measures exposure beside West Wemyss harbour.
Deeper mining context and modern cover. The 2003 mining study’s general column extends down into the Passage Formation, including the Lethemwell Coal above the Castlecary Limestone, and upwards through the Coal Measures. This is the context of underground workings, not a list of formations exposed on this visit. Redistributed colliery spoil and modern beach material must be kept separate from that bedrock hierarchy: they can mix rocks of different source horizons and have no single coal-seam age or local stratigraphic position.
Exposure and interpretation limits. The coastal setting is interrupted by erosion, cover and redistributed material. Neither the regional correlation diagram nor the mining model supplies a bed-by-bed survey at the guide pin. The same caution applies to regional offshore volcanic replacements and inferred deep basin thicknesses: they cannot be turned into harbour units. No formal member is introduced here, and no regional species list is presented as an exact-site fossil inventory.

SAFETY
Check tide times, swell and the weather before setting out, and keep a clear return route. Avoid the foot of cliffs, overhangs and fresh falls; lower cliffs are not automatically safe. Wet shale, algae-covered rock and loose cobbles can be slippery, and industrial debris may have sharp edges. Do not climb spoil faces, enter old workings or disturb unstable blocks.
The official coastal-path information warns of erosion and scrambling on the approach from Dysart towards West Wemyss. That warning concerns the western approach and should inform anyone planning a longer walk; do not assume the entire coast has the same conditions. Children need close supervision, and a visit should be shortened or abandoned when safe path conditions are lacking.
EQUIPMENT
Bring sturdy footwear, tide information, suitable weather protection and a charged phone. A camera, hand lens, notebook and small ruler or scale are useful for observing and recording exposed fossils without disturbing them. Record the wider setting as well as close-up detail. This observation-focused visit does not call for hammers, chisels or equipment for removing blocks.
CLEANING AND TREATING
Leave in-place fossils untreated. Photograph the naturally exposed surface rather than scraping, splitting, washing or applying consolidant to it. Shale can separate along bedding and lose delicate carbonaceous films; attempted cleaning may remove the very feature needed for identification. No blanket glue, varnish or chemical treatment is appropriate for unidentified material. Seek specialist advice from contextual photographs if preservation or scientific importance is uncertain.

ACCESS RIGHTS
Visit for geological observation and photography. A previous refusal of collecting permission has been reported, but the date, landowner, area and activities covered have not been clarified and no reversal has been established. This guide therefore does not recommend collecting here. Follow current signs and established safe routes; the existence of a public coastal path does not establish permission to remove fossils.
The nearby foreshore lies within the Firth of Forth Site of Special Scientific Interest. The guide’s reference point is just landward of the mapped protected strip and is not a property or collecting-area boundary. SSSI designation is not in itself a universal ban on all fossil collecting, but landowner permission and any applicable NatureScot requirements must be established before any collecting proposal. These remain unresolved for this visit.
