Spinostropheus gautieri
Taxonomy
Elaphrosaurus gautieri was named by Lapparent (1960). It is not extant. Its type specimen is MNHN 1961-28. Its type locality is Oued Timmersöi, west of In Tedreft, which is in a Berriasian/Barremian terrestrial horizon in Niger.
It was considered a nomen dubium by Makovicky et al. (2004); it was recombined as Spinostropheus gautieri by Sereno et al. (2004), Carrano and Sampson (2008), Le Loeuff et al. (2012), Serrano-Martínez et al. (2015), Rauhut and Carrano (2016) and Souza-Júnior et al. (2023).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. C. Sereno et al. 2004 | Spinostropheus gautieri is a basal ceratosaurian characterized by mid-cervical vertebrae with strongly canted anterior articular face on centrum (30° angle to posterior centrum face), partitioned anterior pleurocoels, dorsoventrally flattened epipophyseal processes and broad subrectangular neural spines (figure 2b,c). | |
| M. T. Carrano and S. D. Sampson 2008 | Ceratosaur with: (1) strongly canted anterior articular faces on the mid-cervical vertebral centra (30° to posterior centrum face), (2) partitioned anterior pleurocoels, (3) dorsoventrally flattened epipophyseal processes and (4) broad, subrectangular neural spines (modified from Sereno et al. 2004: 1325). |
