Pycnonemosaurus

Pycnonemosaurus (meaning 'dense forest lizard') is a genus of carnivorous theropod dinosaur that belonged to the family Abelisauridae. It was found in the Upper Cretaceous red conglomerate sandstones of the Cachoeira do Bom Jardim Formation, Mato Grosso, Brazil, and it lived during the late Campanian to early Maastrichtian stage of the Late Cretaceous.

== Discovery and naming == The type species, Pycnonemosaurus nevesi, was scientifically described by Kellner and Campos in 2002. The only known specimen (DGM 859-R) was found in a red conglomeratic sandstone at the Jangada Roncador locality (then known as Fazenda Roncador), in Mato Grosso State that is exposed close to Paulo Creek, which is currently referred to the Cachoeira do Bom Jardim Formation. During 1952-1953, Llewellyn Ivor Price visited a farm named "Roncador" in the state of Mato Grosso and collected several dinosaur bones. These remains were found by the owner of the farm, Max de Barros Erhart, and his hired workers at the Paulo Creek site. The most important specimen found was the incomplete skeleton of a large abelisaurid theropod, which was found near several titanosaurid sauropod bones.
