Mystery bone fragment

By | News | No Comments

Fragment of bone found by one of the SDGS members from the Lower Oxford Clay, Peterborough Formation. Finds such as these are extremely difficult to identify in this condition, and it certainly does not take on the appearance of any Oxford Clay marine reptile bone I know of.

Perhaps a rare float and bloat (dinosaur bone element) but without an expert eye run a rule over it, and even then due to its condition it would almost certainly remain a mystery…for now J

Thanks for sharing….David.

Oxford Clay ammonites

By | News | No Comments

With the aid of the Fossils of the Oxford Clay book these ammonites would appear to be Kosmoceras spinosum. Unfortunately the exact location is unknown only the fossils were found from the Oxford Clay of Whittlesea.

Kosmoceras spinosum

Kosmoceras spinosum

Ammonite: Kosmoceras spinosum (?)

Geological Age: Jurassic. 157 myo

Stratigraphic Detail: Middle Oxford Clay

Locality: Whittlesea

Have any other SDGS members collected these in the past.

Actinostreon marshii (Sowerby 1814)

Actinostreon marshii (Sowerby 1814) used to have the genus name Lopha but it is assumed nowadays that this mollusc is not related to the modern day Lophas. The old oysters of this type are presently placed under the family of the Palaeolophidae, which was suggested by Malchus in 1990.

I’ve had this serpulid Serpula sulcata for a few months on loan from a good friend. And now after closer inspection I’m quite sure I can see bioimmurations of the hydroid Protulophila gestroi Roverto indicated by the red arrows.

Thank you “Bill”….still lot’s more fossils to get through.

It’s not that often you get to say “there’s more to this than meets the eye “
