Trilobites are a class of extinct arthropod marine creatures. This specimen is of the genus Flexicalymene which lived between 425-500 million years ago. Flexicalymene are used as an index fossil in the Ordovician Period.
It can be difficult to grasp how long ago these creatures lived. For perspective, dinosaurs lived closer in time to us than these trilobites lived to dinosaurs.
Era: Ordovician (500–425 million years ago)
These photos are representative of our current inventory. You may not receive these exact specimens. We prioritize sending the biggest specimens first.
Thanks to their easily fossilized exoskeletons, we now have a very extensive history of these creatures. We know of about 17,000 species which lived from 521 million years ago until the Permian–Triassic extinction event 252 million years ago.
surprisingly good quality and fast shipping
I bought multiple fossils from Stemcell for my science loving nephew as a birthday gift. They arrived promptly and in super safe packaging. I cannot wait to give them to him and see his reaction. He is going to love them!!! I am very impressed by the quality and price of each fossil. I can’t wait to order more and someday to visit your shop with my nephews. I HIGHLY recommend The Stemcell Science Shop!!! Thank you :)
