Faringdon Sponge Gravels
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 😉
