Many fossil trackways were made by dinosaurs, early tetrapods, and other quadrupeds and bipeds on land. Marine organisms also made many ancient trackways (such as the trails of trilobites and eurypterids like Hibbertopterus).]]> 2018-01-23 19:30:40 UTC https://padlet.com/304870/bxa08l4o2tr3/wish/223974556 304870 https://padlet.com/304870/bxa08l4o2tr3/wish/223975051 A coprolite is fossilized feces.
