TrilobiteKathleen Springer, senior curator of geological sciences at the San Bernardino County Museum, will lecture on “Trilobites: Friend or Foe?” at the Victor Valley Museum in Apple Valley on Sunday, November 24 at 2:00 p.m. The lecture is included with paid museum admission.

Trilobites are an incredibly opportunistic and diverse group of arthropods that inhabited the shallow seas of the Paleozoic Era worldwide, including San Bernardino County. Their beginning was 542 million years ago in the lower Cambrian Period and they continued to prowl the oceans until their untimely demise at the end of the Permian 251 million years ago – a fate they met along with 90% of all organisms on Earth.

“Trilobites are such a great group to teach about—their form, their biology and their distribution globally,” said Springer, “especially those that we find right here in our backyard!”
