Almadasuchus is an
postcranial remains.[1] Almadasuchus was recovered from Puesto Almada , 30 m above the fish beds, dated as Oxfordian in age.[2]
Description
According to a
paraphyletic group of more basal non-crocodyliform crocodylomorphs. Almadasuchus is most closely related to the "sphenosuchian" Junggarsuchus from the Middle Jurassic of China. Almadasuchus is one of only four non-crocodyliform crocodylomorphs known from after the Early Jurassic, the others being Junggarsuchus and two "sphenosuchians" from the Late Jurassic Morrison Formation in the western United States, Hallopus and Macelognathus. Crocodyliforms appeared in the Late Triassic and began a major evolutionary radiation in the Jurassic, making Almadasuchus one of the last non-crocodyliform crocodylomorphs.[1]
Almadasuchus is considered a
exoccipital. These two attachment points probably made the skull of Almadasuchus completely akinetic. Jungarrsuchus, which is the second most closely related non-crocodyliform crocodylomorph to crocodyliforms, has a quadrate that only attaches to the exoccipital.[1]
