This week, our Curator of Collections, Carol Davies, talks about “Trilobite”, prior to Geo Week 2022.
Trilobite lived in marine waters. Some trilobites could swim, others borrowed or crawled around on muddy sea floors. The smallest trilobites were in cm or less in size. The largest trilobites were more than 70cm long.
Trilobites are a group of extinct marine arthropods that first appeared around 521 million years ago, shortly after the beginning of the Cambrian period, living through the majority of the Palaeozoic Era, for nearly 300 million years. They died out at the end of the Permian, 251 million years ago, killed by the end Permian mass extinction event that removed over 90% of all species on Earth. They were very diverse for much of the Palaeozoic, and today, trilobite fossils are found all over the world.
