Abstract
A partial skeleton of a very large coelophysoid previously described is redescribed and named Gojirasaurus quayi n. g. n. sp. The specimen consists of a tooth, dorsals, ribs, chevron, scapula, pubis, and tibia from an individual estimated to be about 5.5m long making it one of the largest known Triassic theropod. The specimen shares several apomorphies with other ceratosauromorphs, including transverse process that extends the length of the centrum, parapophysis and diapophysis on the transverse process, web of bone connecting the tuberculum and capitulum, and a long and narrow pubis. The specimen was collected from the Cooper Canyon Formation (middle Norian).
Kurzfassung
Skelett-Teile eines sehr großen Coelophysiden aus der mittelnorischen Cooper-Canyon-Formation werden als Gojirasaurus quayi n. g. n. sp. beschrieben. Vorhanden sind unter anderem ein Zahn, Wirbel, Rippen, Haemapophysen, Scapula, Pubis und Tibia eines insgesamt etwa 5,5 m langen Skeletts. Mehrere Apomorphien verbinden das Taxon mit anderen Ceratosauromorphen.
