I'm a palaeontology student in Portsmouth, UK. Recently I visited a locality in SW england called Aust cliff. It represents a marine transgression in the upper triassic (the rhaetian). There are several "bone beds" within the expose. The bone beds are known to contain fragmentary remains of marine reptiles, fish, and even dinosaurs.
On my trip I did indeed find some bone. Me and my tutor agree that the texture is reptilian, but cant seem to connect it to a particular animal, or shed much light on which part of the skeleton it may come from .
Here is a picture:
If anyone has any ideas I would be very pleased to hear them! Thanks
One observation that may not come across well in the photo is that it does appear to be rather thin....maybe no more that 5mm or so, although I will have to prepare it more to know exactly.
