phymosoma raguini (fossil Echinoidea) (Lambert 1931) Jurassic urchin

This is a gorgeous large sea urchin fossil (rare at this size) perfectly preserved with obvious care and attention taken to expose all the intricate detail. One hairline crack to side, strong and stable. Caused during the millions of years of the fossilisation process.

Sea urchins have been living in our seas and oceans for millions of years. These types of Echinoidea fossils are a popular specimen of these types because of how well preserved they are, with all of the hard shell well formed and preserved during the fossilisation process. These urchins are found specifically and most commonly in the mid section of the Atlas Mountains in Morocco and date back to the Jurassic times between 201-145 million years ago. This particular fossil was found at (Missour) These types of fossils vary in size with the larger and more rare finds realising 100s of pounds in price. This fossil is a nice large size to be able to appreciate its detail which is superb. Sea urchins, are typically spiny, globular animals, echinoderms in the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to 5,000 metres. The hard shells are round and spiny, usually from 3 to 10 cm across.
