Ichnotaxon comes from the Ancient Greek ἴχνος (íchnos) meaning "track" and English taxon, itself derived from Ancient Greek τάξις (táxis) meaning "ordering". [ 1 ] Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils , more commonly known as trace fossils ( fossil records of lifeforms ...
Sphingopus type footprints are known from two locations. Fossils dating 228–245 million years have been recovered from what appears to have been a lagoon in the Grès d'Antully Formation in Saône-et-Loire, France.
Anticheiropus is an ichnogenus of dinosaur footprint belonging to a saurischian. [1] It has only been discovered in Massachusetts (Portland Formation, Newark Supergroup).Two ichnospecies are known (both are known from a single footprint): [2] [3] A. hamatus and A. pilulatus, both discovered around 1863 and named by Edward Hitchcock in 1865.
Ceratopsipes goldenensis is an ichnospecies of dinosaur footprint, described in 1995 from the Laramie Formation in Colorado. [1] It is represented by massive pes prints approaching 80 centimetres (31 in) in width.
Strictly speaking, an ichnospecies is the name of the trace fossil, not of the animal that made it. An international team's discovery of a set of 1.5 million-year-old human ancestor footprints in Ileret, Kenya provides the earliest direct evidence of a modern human style of upright walking.
Saurexallopus (meaning "reptile different foot") is an ichnogenus of four-toed theropod footprints from the Late Cretaceous period. The type ichnospecies is S. lovei, named and described in 1996 from the Harebell Formation. [1] The taxon was originally named Exallopus, but later renamed as Saurexallopus as the former was preoccupied by a ...
A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.
