Venetoraptor (meaning "Vale Vêneto plunderer") is an

archosaurs from the Late Triassic Santa Maria Formation (Paraná Basin) of Rio Grande do Sul, Brazil. The genus contains a single species, V. gassenae, known from a partial skeleton.[1]

Discovery and naming

The Venetoraptor

caudal vertebrae, a partial pelvic girdle, and elements of the arms and legs.[1]

In 2023, Müller et al.

lagerpetid archosaur based on these fossil remains. The generic name, "Venetoraptor", combines a reference to the tourist locality "Vale Vêneto" with the Latin word "raptor", meaning "plunderer". The specific name, "gassenae", honors Valserina M. B. Gassen, a founder of the paleontology center at the Federal University of Santa Maria.[1]

Description

Size of Venetoraptor compared to a human

Venetoraptor is estimated at 96.1 centimetres (37.8 in) long, and 33.4 centimetres (13.1 in) tall at the hip. The

Dromomeron romeri, metacarpal III is the longest. The hands of Venetoraptor bear long, scythe-like claws. Like other lagerpetids as well as early pterosaurs, its vertebrae are proportionately short.[1]

Paleobiology

The recurved beak and grasping hands with large claws of Venetoraptor may indicate a

scansorial lifestyle, allowing it to climb and consume food more easily. Birds with raptor-like beaks are more adapted for tearing flesh and the consumption of hard fruit. However, whether the diet of Venetoraptor followed similar trends is unknown. Details of the arms and legs support the loss of obligatory quadrupedalism in Venetoraptor and its relatives, so a bipedal lifestyle is more likely.[1]
