“…Anterior cervical ribs are thin and very long extending over at least two succeeding centra. Posterior cervical ribs grade to stouter and plowshare shaped (RENESTO 1994). 17 dorsal vertebrae are present; they are much shorter than the cervicals, with rather low, rectangular neural spines.…”

“…As for other known prolacertiforms, no olecranon is present. The carpus is rather poorly ossified: only three rounded bones are present; On topotogical grounds they can be tentatively identified asa rather large ulnare and a much smaller ?third distal carpal anda radiale (RENESTO 1994). The metacarpals are featureless rod-like bones that increase in length laterally apart for the fifth, which is the shorter.…”

A long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non‐archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals. Among all tetrapods both extant and extinct, two Triassic archosauromorphs, Tanystropheus and Dinocephalosaurus, have necks that are particularly elongated relative to the lengths of their trunks. However, the evolutionary history of such hyper‐elongated necks in these two archosauromorph clades remains unknown, partially because known close relatives such as Macrocnemus and Pectodens possess only moderately elongated necks. Here, we describe a newly discovered early diverging archosauromorph, Gracilicollum latens gen. et sp. nov., based on a specimen comprising a partial neck and an incompletely preserved skull. The long neck is composed of at least 18 cervical vertebrae. The dentition suggests that this new taxon most likely represents an aquatic piscivore, similar to Dinocephalosaurus and Tanystropheus hydroides. Despite possessing a high number of cervical vertebrae, Gracilicollum gen. nov. is recovered as a tanystropheid in an evolutionary grade between Macrocnemus and Tanystropheus rather than as a close relative of Dinocephalosaurus, a result that is primarily attributable to the presence of palatal teeth and the anatomy of the cervical vertebrae in Gracilicollum gen. nov. Considering the information provided by the new specimen, we provide a detailed discussion of the cervical evolution in dinocephalosaurids and tanystropheids, which is shown to be highly complex and mosaic in nature.
