Vertebrate tracks provide valuable information about animal behavior and environments. Swim tracks are a unique type of vertebrate track because they are produced underwater by buoyant trackmakers, and specific factors are required for their production and subsequent preservation. Early Triassic deposits contain the highest number of fossil swim track occurrences worldwide compared to other epochs, and this number becomes even greater when epoch duration and rock outcrop area are taken into account.

A perfectly preserved amber fossil from Myanmar has been found that provides evidence of the earliest grass specimen ever discovered -- about 100 million years old -- and even then it was topped by a fungus similar to ergot, a hallucinogen which for eons has been intertwined with animals and humans. Among other things, it gave us the psychedelic drug LSD.
