Neovenator

Hutt et al., 1996 NEE-oh-ve-NAY-tor

From Latin neo- ('new') and venator ('hunter'), meaning 'new hunter'

125.8–121.4 million years ago Barremian, Early Cretaceous
Early Cretaceous stages

Neovenator is an extinct genus of carcharodontosaurian theropod dinosaur. It is known primarily from several skeletons found in the Early Cretaceous (Hauterivian-Barremian) Wessex Formation on the south coast of the Isle of Wight, southern England. The first remains of Neovenator were discovered in 1978 alongside those of the ornithopod Brighstoneus, after the collapse of part of Grange Chine. In 1996, Steve Hutt, David Martill and Michael Barker named the genus Neovenator. One species is known: the type species, N. salerii, after the Salero family who owned the site on which its remains were discovered.

Under dispute

Most analyses recover Neovenator salerii in Carcharodontosauria, as its earliest member (Brusatte and colleagues 2008), as the sister of Carcharodontosauridae (Aranciaga Rolando and colleagues 2024), or with Chilantaisaurus in Neovenatoridae (Carrano and colleagues 2012; Rauhut and colleagues 2024), a clade that once also held the megaraptorans, now mostly placed in Coelurosauria. Kellermann and colleagues (2025) recover Carcharodontosauria under some weightings only, finding Neovenator elsewhere lower in Allosauroidea, and Apesteguía and colleagues (2016) once recovered it outside Allosauroidea, a result they call in need of further testing. It is placed at Allosauroidea incertae sedis.

Diagnosis

  1. Premaxilla with an accessory peg-and-socket interpremaxillary articulation in the dorsal symphyseal region
  2. Maxilla with an enlarged maxillary fenestra about one-sixth the length of the maxillary tooth row
  3. Scapulocoracoid glenoid fossa wider mediolaterally than long anteroposteriorly
  4. Distal ischial boot with the left and right ischia conjoined anteriorly but diverging posterolaterally
  5. Femoral head oriented anteromedially and inclined proximally
  6. Thumbprint-shaped depression on the posterior femoral shaft lateral to the proximal end of the fourth trochanter
  7. Robust suboval ridge on the external surface of the lesser trochanter of the femur
