Welcome back to Trilobite Tuesday. By the time they arrived in Earth's early waters, trilobites already possessed a hard outer shell, sophisticated eyes, and even a basic respiratory system. However, this 520-million-year-old Olenellus, which features a multi-segmented opistothorax extending from its tail, is evidence of these arthropods’ more primitive, worm-like predecessors.
This Fossil Friday is a blast from the past! Snapped circa 1988, this photo depicts Tyrannosaurus rex and Triceratops on display in the Museum’s Hall of Late Dinosaurs. These iconic dinosaurs are still on display at the Museum, but they now sit in separate halls. You can find T. rex in the Hall of Saurischian Dinosaurs—saurischians are characterized by grasping hands, in which the thumb is offset from the other fingers. Triceratops is in the Hall of Ornithischian Dinosaurs, which displays dinosaurs that are characterized by a backward-pointing extension of the pubis bone. This bone was thought to have helped support the enormous stomachs that these animals needed to digest masses of tough vegetation!

Known as the Jarkov Mammoth, this specimen was found in Siberia. The 23 tonne block of mud and ice was lifted to an ice cave where the mammoth inside was recovered and studied.
