Concavenator corcovatus

Reptilia - Avetheropoda - Carcharodontosauridae

Taxonomy
Concavenator corcovatus was named by Ortega et al. (2010). Its type specimen is MCCM-LH 6666, a skeleton, and it is a 3D fossil preserving soft parts. Its type locality is Las Hoyas Unit 3 (MCCM collection), which is in a Barremian lacustrine - large limestone/packstone in the La Huérguina Formation of Spain. It is the type species of Concavenator.

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
F. Ortega et al. 2010A carcharodontosaurian having four recesses, three of them connected, on the nasal bones; a large, rounded, thickened postorbital brow occupying one-third of the orbit; tall neurapophyses of the eleventh and twelfth dorsal vertebrae (five times the height of the centra); relatively high, cranially directed neurapophyses of the second and third caudal vertebrae; and a small, thorn-like caudal process at the base of each neurapophysis of the proximal caudal vertebrae. In addition, Concavenator presents a unique combination of characters: the heavily rugose (wrinkled) dorsal surface of the nasal bone, shared with more derived carcharodontosaurids and abelisaurids; the anterior end of the jugal bone posterior to the internal antorbital fenestra; the thick dorsoventral anterior process of the lacrimal bone; light rugosity on the lacrimal horn; no fenestra on the lacrimal bone; the anteriormost point of the lateral lamina of the ventral process in the lacrimal situated dorsal to the mid-height of the ventral process, with a distinct rugose patch on the lateral surface; no suborbital process on the lacrimal bone; weak enamel wrinkles on teeth adjacent to the carinae that do not extend across the labial and lingual tooth surfaces, (shared with Tyrannotitan and carcharodontosaurines); no crown recurvature, (shared with carcharodontosaurines); accessory centrodiapophyseal lamina on the transverse processes of the posterior dorsal vertebrae, (shared with baryonychines); the prominent rugose distal tubercle on the ischium (part of the hip bone); quill knobs in the posterolateral margin of the ulna, (shared with derived maniraptorans); and the preacetabular blade of the ilium having a convex ventral portion of the cranial edge and hook-like ventral process, (shared with tyrannosaurs).
M. T. Carrano et al. 2012Allosauroid with: (1) four pneumatic recesses in nasal, three of which are connected; (2) rounded postorbital brow occupying one-third of orbital fenestra; (3) dorsal vertebrae 11–12 with neural spines five times centrum height; (4) caudal vertebrae 2–3 with tall, anteriorly angled neural spines; and (5) pollex terminates at or below distal end of phalanx I of digit II (all from Ortega et al. 2010).
