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.

Actinostreon marshii (Sowerby 1814)

By | News | No Comments

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.

“there’s more to this than meets the eye “

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 “
