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 “

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 “

A fine example showing a section of the bony-scaled fish Lepidotes latifrons from the Mid Jurassic, Lower Oxford Clay (Peterborough Formation) found by one of our SDGS members. This fossil is allocated to go on permanent display for all to see…

Stamford and District Geological Society Database

By | News | No Comments

We are proud to announce a, soon to be released Database for members fossil collections designed by Stamford and District Geological Society member Richard Forrest (website designer for the “The plesiosaur site”) and (database designer for “CBRP Ltd”) .The Database has been crafted to reflect what fossils our members have found in the past. But also builds upon technology capable of addressing future fossil finds.

For further information and If you would like to become involved with this exciting project then head over to the “web editor” email link below and let us know.

The famous Faringdon sponge

By | News | No Comments


115 million years old

Faringdon Sponge Gravels
Faringdon, Oxfordshire

These gravels were formed during the Cretaceous period when the area was submerged beneath the sea. Sponges lived on the sea floor and when they died underwater currents swept them into hollows where they accumulated to form the gravels.

The Faringdon Sponge Gravels is part of the Lower Greensand. It is composed predominantly of the remains of calcareous sponges, with brachiopods, echinoderms and bryozoa. Derived fossils such as reptile bones from older formations also occur such as a partial Ichthyosaur rostrum I have (I think that’s what it is at present).

I’ve only lightly dusted them as they will make a great prepping project for someone to pick out all the tiny pieces of gravels.

Except for this one as an example which I believe to be the sponge Raphidonema Faringdonense, a classic fossil from the Faringdon Sponge Gravels.

These specimens are from an old collection and were collected at the date below give or take a few weeks. ​ I’ve decided to keep the old newspaper that the fossils were wrapped up in with the fossils for future generations to read.

Thank you for bringing them to light T&J 😉
