Dr. Luis Buatois (Ph.D.) traces a series of hexagons with his finger, following the path carved by tiny organisms millions of ...

Organisms in the deep sea rely on gravity flows to lay down sediment and then make burrows beneath the seafloor, according to ...

Tropical riparian ecosystems—those found along rivers and wetlands—recovered much faster than expected following the ...

If an external mold later fills with sediment or minerals, it can form a cast. Trace fossils are other kinds of evidence that an organism existed. Trace fossils include tracks, trails and footprints; ...

Fossil evidence from North China suggests that some ecosystems may have recovered within just two million years of the ...

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 ...

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 ...

Trace fossils, such as millimeter-sized burrows, provide insights into the evolution of deep marine ecosystems. These fossils, remnants of ancient organisms' activities, reveal how deep-sea ...

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 ...
