trilobite
n 1: an extinct arthropod that was abundant in Paleozoic times;
had an exoskeleton divided into three parts

The Collaborative International Dictionary of English v.0.48 (gcide)

Trilobite \Tri"lo*bite\ (tr[imac]"l[-o]*b[imac]t), n. [Cf. F.
trilobite. See {Trilobate}.] (Paleon.)
Any one of numerous species of extinct arthropods belonging
to the order Trilobita. Trilobites were very common in the
Silurian and Devonian periods, but became extinct at the
close of the Paleozoic. So named from the three lobes usually
seen on each segment.
[1913 Webster]

Could trilobites still be alive? Any sightings of them?
Trilobites are probably the most famous type of creature that is said to have died out during the Permian-Triassic Extinction event 250 million years ago, but given the vastness of the ocean and the fact that we've only explored very little of it, I think it's possible for the trilobite to still be alive
