This partially enrolled Proetus is another trilobite from the limestones of the Anti-Atlas Mountains in Morocco. It was purchased at a fossil shop with no information, for a few pence. The location is unknown and the data is broadly Devonian.
Hollardops mesocristata is a Devonian trilobite commonly found in the Anti-Atlas Mountains from the Hamar L’aghdad limestone, Morocco. This is a fair specimen, damaged by clumsy excavation. There are large numbers of these fossils being sold world-wide. Occasionally a very fine and well-preserved specimen is available, but fine specimens are rare since the main strata containing these trilobites are being mined for fast turnover and quick sales to tourists and traders.
These two fragments of bone were found amongst the Farringdon Sponge Gravels. They appear Reptilian in their form and preservation. The Farringdon Sponge Fossils were old fossils re-deposited on the sea bed at a time contemporary with the Cambridge Greensand during the Cretaceous. These bones are likely to come from Cretaceous marine reptiles, being deposited at the time of the redistribution of older fossils.
This fish vertebra was found amongst the fenland deposits near Spalding in Lincolnshire. Only the centrum is present and the processes have been lost prior to preservation. The specimen is a few thousand years old and very difficult to classify. All I have been able to suggest is that this is the vertebra of a large freshwater fish. It shows similarities with the vertebrae of Pike.
