Lusovenator santosi
Taxonomy
Lusovenator santosi was named by Malafaia et al. (2020). Its type specimen is SHN.036, a set of postcrania (a partial postcranial skeleton preserving odontoid, atlantal intercentrum, a cervical vertebra (previously misinterpreted as the articulated axial intercentrum ), and it is a 3D body fossil. Its type locality is cliffs north of Praia de Valmitão, which is in a Kimmeridgian fluvial mudstone/sandstone in the Praia da Amoreira-Porto Novo Formation of Portugal. It is the type species of Lusovenator.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. Malafaia et al. 2020 | A carcharodontosaurian theropod diagnosed by the following autapomorphies (the diagnosis is only based on the type specimen, SHN.036): large recesses in neural arch of anterior dorsal vertebrae; well-developed and continuous longitudinal laminae extending from the tip of the prezygapophyses to the distal end of the postzygapophyses in mid-caudal vertebrae; and supraacetabular crest of ilium forming a prominent ventrolaterally projecting shelf. Additionally, Lusovenator differs from other carcharodontosaurs in the following unique combination of features: absence of ventral keel on anterior dorsal vertebrae; presence of hyposphene-hypantrum articulation in at least the anterior-most caudal vertebrae; presence of a lateral lamina projecting from posterior articular facet to base of caudal rib in mid-caudal vertebrae; mid-caudal vertebrae with spinoprezygapophyseal lamina projecting from the medial surface of the prezygapophysis; and almost flat ventral surface of the pubic boot. |
