Happy National Fossil Day! Here’s a recent fossil sent in by Rockwatcher, Ronnie for identification which is likely to be a part of a bivalve shell, Trigonia costata, named by chemist and palaeontologist James Parkinson whose name lives on in Parkinson’s disease. It is a species that appeared first in the Toarcian Stage (end of the Early Jurassic), but persisted into the Middle Jurassic – which is probably the age of...
Michele’s Calcite Crystals from Lulworth Cove

Sending in details about her specimen for further investigation, Michele wondered if her rock might be fossilised wood, grass or plant matter. Rockwatch Ambassador Michael explains that clues to its form lie in its fibrous appearance as well as its location. Resembling the fibrous texture of beef,...
Lana’s Nodule of Marcasite

Rockwatch Ambassador, Michael, confirms that Katie’s fossil, “is a piece of fairly large Jurassic Belemnite”. So, what’s a Belemnite? Belemnites were an extinct marine animal that looked very like a modern-day squid except that they also had an...
