Lately, The whole lot Dinosaur was contacted by Lee who had collected an odd rock while visiting Yorkshire. Lee requested what the rock might be and despatched in some pictures. We contacted Lee and requested him to ship in some extra footage, however this time together with an object similar to a coin that might present a scale. In our e-mail, we requested the place this rock was discovered.
Robin Hood’s Bay Fossil
Lee commented that this rock was discovered at Robin Hood’s Bay on the north Yorkshire coast. This is part of the world we all know fairly effectively and it’s well-known for its fossils. The Redcar Mudstone Formation dominates the geology of this a part of the English coast and we suspect that the rock is mudstone and the bizarre object is the remnants of a Jurassic shelly invertebrate.
Decrease Jurassic
The shales, mudstones and sandstones that outcrop at Robin Hood’s Bay date from the Decrease Jurassic (Sinemurian to Pliensbachian fauna phases) and we suspect that this fossil is round 195 – 185 million years previous.
The specimen is closely eroded, and we expect it’s being considered as a cross-section. Ammonites are comparatively widespread on this stretch of shoreline as are Gryphaea fossils (Devils toenails) and crinoids. It is rather tough to determine this merchandise, simply from the images, nevertheless, we expect that as there appear to be striations (strains) seen within the fossil that it is a extremely eroded bivalve.
Any Ideas
We all know that a lot of our weblog readers are enthusiastic fossil collectors. We might welcome any recommendations and assist with the identification of this specimen.
