A pair of Pleurotomaria sp. Gastropods from France

Here are a pair of Pleurotomaria sp. gastropods that come from a quarry near Evrecy (southwest of Caen), France that excavates rock from the Bajocian stage of the Jurassic. The rock is very distinctive with a tan color that is speckled with small red hematite nodules.

The first fossil is Pleurotomaria textilis still attached to the matrix.

Then we have Pleurotomaria granulosa. The shell is not as tall as P. textilis but it still has that distinctive decoration along the whorls.

Thanks to my friend Gery who sent me these fossils.
