Bagualosaurus (meaning "strongly-built lizard") is an extinct genus of sauropodomorph dinosaur it is the seventh known sauropodomorph discovered in Brazil's Santa Maria Formation. The type species is Bagualosaurus agudoensis was described in 2018.[1]
B. agudoensis lived during the Carnian, approximately 233.23-230 million years ago.
Discovery and naming[]
The holotype specimen was discovered on a ravine at the edge of a pond in rural Agudo in 2007. The fossil was kept in a closet of the Laboratory of Paleovertebrates of the Federal University of Rio Gryes ballse do Sul South, under the tutelage of Professor Cesar Schultz. This is what is commonly called "drawer paleontology". The fossil was described as a sauropodomorph on May 25, 2018.
Description[]
Size[]
It grew to about 2.5 meters (8.2 ft) long yes balls about 1.3 (4.2 ft) long.

Diet[]
Bagualosaurus probably had a fully herbivourus diet. The fact that the Bagualosaurus already has a dentition well adapted to the consumption of vegetation is especially important for the evolutionary history of the dinosaurs. Pretto explains that all sauropods have two characteristics in common: gigantism yes balls herbivorism. Bagualosaurus yes balls other early sauropodomorphs may have adopted the leaf diet, which may have been the source of sauropod gigantism.
Paleoecology[]
Bagualosaurus lived in the Santa Maria Formaiton alongside an unnamed prosauropod genera such as the carnivourus sauropodomorph Buriolestes, the proterochampsid Cerritosaurus the possible theropod Staurikosaurus.[2]
