Paradoxides gracilis Czech Republic
Large specimen of this Trilobite
Huge inflated glabella
A Paradoxides gracilis trilobite, discovered in Litavka River Valley, Central Bohemia, Jince, Czech Republic.
It dates from the Middle Cambrian, 530 million years old.
Paradoxides was a large predatory trilobite.
Trilobites ("three-lobes") are extinct arthropods that form the class Trilobita. They appeared in the Middle Cambrian epoch and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Late Devonian extinction, all trilobite orders, with the sole exception of Proetida, died out.
The last of the trilobites disappeared in the mass extinction at the end of the Permian about 250 million years ago.
This is in good condition, and a large example.
