The burrows are often marked with chevron patterns showing the upward direction the organisms were tunnelling. Praedichnia : [ 9 ] trace fossils that show evidence of predatory behaviour, such as the drill holes ( borings ) left in shells by carnivorous gastropods , or more dramatically, the bite marks found on some vertebrate bones .

Various species through their footprints that are characterized by the association of two impressions left by hand and foot.
Anomoepus is the name assigned to several fossil footprints first reported from Early Jurassic beds of the Connecticut River Valley, Massachusetts, US in 1802. Map showing tracks of Anomoepus (green) and Grallator (blue) in Moyeni. All four feet have left impressions. The smaller forefeet have five toes, whereas the larger hind feet have three ...
