Quote:Trilobites are hard-shelled, segmented members of the phylum Arthropoda and the class Trilobita that appear in the fossil record for almost 300 million years—from about 540 to 251 million years ago (mya). They existed throughout almost all of the Paleozoic era, flourishing in the earlier part of it and slowly declining in the later part, finally going extinct in the Permian-Triassic extinction event about 251 mya.

Quote:Many species of Pleistocene megafauna, like the woolly rhinoceros, became extinct around the same time period. Human and Neanderthal hunting is often cited as one cause.[6] Other theories for the cause of the extinctions are climate change associated with the receding Ice age and the hyperdisease hypothesis.[7]
Recent radiocarbon dating indicates that populations survived as recently as 8,000 B.C. in western Siberia.

Please get your head out of your ass....or at least get it out of creationist drivel and face reality.
