Paradoxides
Paradoxides was a trilobite, an old sea creature with a hard, flat shell split into many parts. It had a round head with long, curved spines at the sides and lots of spiky segments down its back. It crawled on the sea floor more than 500 million years ago, long before there were any fish with jaws or dinosaurs.

Fun facts
It was one of the biggest trilobites. The record fossil is 37 centimetres long, longer than a school ruler.
Its eyes were shaped like crescent moons and could see almost all the way around it, but only sideways, not up.
Its back was made of 19 to 21 segments, each with a long spine curving backwards.
To grow, it wriggled out of its old shell through the front, like taking off a jumper.
Its baby started out as a tiny disc with three pairs of spines around the edge.
