Trace Fossil – Burrow, Blea Wyke Sandstone Upper Lias Toarcian Jurassic, Rosedale Yorkshire UK – Genuine Specimen with COA

Trace Fossil – Burrow, Blea Wyke Sandstone Upper Lias Toarcian Jurassic, Rosedale Yorkshire UK – Genuine Specimen with COA

£12.60

Now available is a rare and scientifically notable trace fossil burrow, collected from the Blea Wyke Sandstone Formation of the Upper Lias (Toarcian Stage), Jurassic Period, found in Rosedale, North Yorkshire, United Kingdom. This trace fossil captures the preserved activity of a burrowing organism—likely a marine invertebrate—that lived over 180 million years ago.

Fossil Type:

  • Ichnofossil (Trace Fossil)
  • Burrow structure, unidentified ichnogenus (potential affinities to Thalassinoides, Planolites, or Ophiomorpha based on morphology)

Geological & Stratigraphic Context:

  • Formation: Blea Wyke Sandstone Formation
  • Group: Whitby Mudstone and equivalents
  • Stage: Toarcian (Upper Lias, Lower Jurassic)
  • Age: Approx. 183 to 174 million years ago
  • Location: Rosedale, North Yorkshire, UK
  • Depositional Environment: Shallow marine shelf and deltaic settings with sand-rich deposition during periods of sea-level fluctuation and oxygenation recovery following the Toarcian Oceanic Anoxic Event
  • Lithology: Fine to medium-grained sandstones with occasional silt and clay laminations

Morphological Features:

  • Visible horizontal to sub-vertical tubular burrow trace in sandstone matrix
  • Smooth or pellet-lined burrow walls, dependent on trace originator
  • Evidence of sediment displacement or infill
  • Reflects behavioral patterns such as dwelling, feeding, or locomotion of marine benthic organisms

Scientific & Collector Relevance:

  • Trace fossils from the Toarcian provide important insight into post-anoxic recovery ecosystems and invertebrate adaptation
  • Burrows such as these are used in ichnofacies analysis to interpret Jurassic sedimentary environments and paleoecology
  • The Blea Wyke Sandstone is a lesser-known but fossiliferous unit within Yorkshire’s globally important Jurassic coast

The specimen is shown in photographs with a 1cm square scale cube, and you will receive the exact piece displayed. It was chosen for its clear trace detail and stratigraphic integrity.

Authenticity Guaranteed: All our fossils are 100% genuine natural specimens and include a Certificate of Authenticity. This is an ideal addition to any collection focused on Jurassic paleoenvironments, sedimentology, or invertebrate ichnology.

Please view all photos for accurate sizing and details. A unique opportunity to acquire a real Jurassic burrow trace fossil from the historic fossil beds of North Yorkshire.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
