Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
According to Milan et al. (2016) [1] the diagnostic characters Limnopus are: Track-ways of a quadrupedal tetrapod with plantigrade to semiplantigrade imprints, pace angulation 80°–96°, stride : pes length = 3–5.5 : 1; pes impressed closely behind manus, pentadactyl, digits increasing in length from I–IV, digit IV longest, digit V as ...

Gwyneddichnium corresponds to footprints from a quadrupedal animal with a small pentadactyl (five-fingered) manus (hand) and a notably larger five-toed pes (foot). The manus and pes are mesaxonic, meaning that the third digit is the longest digit, followed by the subequal second and fourth digits.
The former two data when calculated together (neopallium surface/cerebrum surface) compose 61.6% in the total neocortical surface area of the brain, meaning that adult Anoplotherium has massive brain and neocortical surface area measurements compared to most Palaeogene artiodactyls, the latter measurement being on par with or less than those of ...
Amphimerycidae is an extinct family of artiodactyls that was endemic to western Europe that lived from the Middle Eocene to the Early Oligocene.With a taxonomic history extending as far back as 1804, the family was formally recognized by the Swiss palaeontologist Hans Georg Stehlin in 1910 and contains two genera: Amphimeryx and Pseudamphimeryx.
