About 95 tracks have been attributed to Minisauripus, and over 80% of them were less than 3 cm (1.2 in) long.The abundance of such small footprints might suggest that the trackmaker of Minisauripus was a small non-avian theropod, not a juvenile of a larger taxon. [4]
When referring to trace fossils, the terms ichnogenus and ichnospecies parallel genus and species respectively. The most promising cases of phylogenetic classification are those in which similar trace fossils show details complex enough to deduce the makers, such as bryozoan borings , large trilobite trace fossils such as Cruziana , and ...
The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, HaMakhtesh HaKatan, southern Israel. An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact.
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 ...
Ichniotherium (meaning "marking creature") is an ichnogenus of tetrapod footprints from between the Late Carboniferous period to the Early Permian period attributed to diadectomorph track-makers. [ 1 ] [ 2 ] These footprints are commonly found in Europe , and have also been identified in North America and Morocco .
The lack of claws and scales suggest that these footprints were made by large amphibians, being often attributed to eryopid temnospondyls. [ 1 ] [ 2 ] [ 3 ] The lack of belly and tail marks in the sediment indicates that the producer raised most of its body when walking and had a short or non-dragging tail.
Dromopus lacertoides tracks are characterized by five-fingered hand and foot imprints up to 6 centimetres (2.4 in) long, about a third longer than they are wide, with a short palm and long, slender, tapered digits. The length of the digits increases from the first to the fourth, with the fifth having the same length as the second.
