Pycnonemosaurus is an abelisaurid theropod dinosaur from the Late Cretaceous of Brazil. It was named in 2002 by Alexander Kellner and Diogenes de Almeida Campos. It was one of the largest abelisaurids to walk the Earth, only beaten in size by 2 unnamed genera related to it.
Pycnonemosaurus was a giant theropod with a bulky body, a moderately long tail, extremely short (almost non-existant) arms with 4 clawless fingers on each hand, and a mid-sized head with a mouth containing lots of small teeth. Its body would have been covered in scaly skin.
Pycnonemosaurus was a predator, preying on mid-sized sauropods, small crocodylomorphs, and dromaeosaurs. Its teeth were small yet sharp, and were used to get a hold of struggling prey as the abelisaur shook and tore them apart.
