Fossils can be broadly divided into body fossils and trace fossils. Body fossil – The remains of part (or all) of an actual organism. In the kits, the trilobite (2), brachiopod (3), dinosaur bone (4), ...

A new analysis of fossil footprints suggests that the 2-meter-tall, 4- to 5-meter-long carnivores that left them could run nearly 45 kilometers per hour, bolstering the evidence that at least some ...

Preserved footprints, also known as ichnites, are a type of trace fossil and a window into the lives of dinosaurs. They formed in the same way our footprints do when walking on soft ground like mud.

This can include fossil bones, claws, teeth, shells, tree trunks and leaves. Other fossilised signs of a plant or animal are called trace fossils. These can include imprints of skin or feathers, eggs ...

To reconstruct the timeline of ecosystem recovery on land, Tian and colleagues analyzed trace fossils (such as burrows and footprints), plant remains and vertebrate fossils preserved in ...
