Scientists have identified a new species, *Labrujasuchus expectatus*, a crocodile relative from the Triassic Period that resembled an ostrich-like dinosaur. This ancient creature walked on two legs and had small forelimbs. Its mouth ended in a beak and lacked teeth.
This discovery is surprising because *Labrujasuchus* belongs to the archosaur lineage that includes modern crocodiles. Crocodiles are known for their four-legged bodies and tooth-filled jaws. The new species looked almost nothing like its modern relatives.
The Triassic Period was a time of significant evolutionary experimentation. Many major animal groups began to evolve. This era featured unusual creatures with diverse body shapes and lifestyles.
*Labrujasuchus expectatus* is the newest known member of Shuvosauridae. This small group of ancient crocodile relatives evolved body plans similar to bipedal theropod dinosaurs. This occurred despite their belonging to a different branch of the reptile family tree.
Only five shuvosaur species have been identified to date. *Labrujasuchus expectatus* fills a predicted evolutionary gap. Researchers had found shuvosaur fossils from older and younger rock layers in the region. This suggested that additional species likely existed in between.
Ghost Ranch in New Mexico is a significant site for Triassic fossils. It continues to yield well-preserved specimens from the Late Triassic. Studying these early evolutionary forms helps scientists understand how life developed and adapted over time.
