Trace Fossils and what they tell us | A lecture by Dr. Jon Noad

Trace fossils were once considered second rank fossils and many are still overlooked by aficionados while searching in the field for past life fossilized (body fossil) remains. This has gradually changed, especially with the help of beautiful outcrops of dinosaur footprints. These, as all other trace fossils, have the characteristic of having been produced by alive organisms as part of their daily activities: walking, eating, reproducing, hiding, etc. In this sense, they are complementary of body fossils because they disclose behavior (and a bit also of morphology) of past organisms. However, they are not always easy to attribute to a specific extinct species. Nevertheless, their current status and interest have much increased and paleontologists are increasingly paying more attention to them.
