Odd shape Lampshell

By | News | No Comments

Bill,

These Silurian brachiopods with additional note in the matchbox below that holds them Is all the associated information there is. What I have noticed is those indicated with the “white arrow” would appear to have the same appearance as each other.

What I have noticed is those indicated with the “white arrow” below would appear to have the same appearance as each other.

But the one indicated by the “red arrow” above looks more bulbous and not flat on the bottom.

They are all probably Atrypa, possibly Atrypa reticularis. However there are other Atrypids and internal details may be required for confident identification.

Does anyone think that there may be two different species here?

Rescued from cardboard eating critters

Hi Bill,

I’ve delved into this intriguing matchbox of fossils.

It’s quite possible this gastropod below could be a Neptunea species maybe Neptunea lyrata?
If I’m not wrong, Neptunea is present in the Pleistocene Red Crag.

As for the other gastropod below, well the jury is still out on that one, needless to say though they are both rehoused in a new box.

Away from those pesky cardboard munching critters.

…..just a thought, perhaps Mr Crowson may know I’ts identity 😉

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)

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 “

By | News | No Comments

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 “

Regards,

Darren 🙂
