FOSSIL SPONGES 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 with the fossils for future generations to read.

From the album: Holzmaden
This seems to be a kinda rare find because maybe these are plesiosaur bones. Plesiosaur is the rarest marine reptile in the area of Holzmaden so I am pretty happy with this find On the plate are two ribs, a phalange and an interclavicle. But I am far away from being with the ID although I already showed it too some local experts. Its from the quarry Kromer near Holzmaden (Lower Jurassic, Posidonia Shale). Unprepped: Some more pictures of the prepped specimen: -
From the album: Holzmaden
These are two crocodile vertebrae from the lower Jurassic (Posidonia Shale) from the quarry Kromer near Holzmaden. The bigger one is about 8 cm long. Here is a picture of the unprepped fossil: The prep work took about 10 hours. I am very pleased with this find because in general crocodile bones are much rarer than Ichthyosaur bones in Holzmaden.
