Sereno et al
Synonyms: Elaphrosaurus gautieri
In Tedreft, Niger
(Gautier's spined vertebrae)Etymology
is derived from the Greek "Spinos" (spine) and "strophe" (vertebra), referring to the prominent bony processes (known to boffins as epipophyseal processes) on the top of its neck (cervical)
The species epithet
, was coined by Lapparent in 1960 to honor F. Gautier who discovered the type locality at In Tedreft, Niger, in 1959.
The first remains of Spinostropheus
were discovered at Oued Timmersöi, west of In Tedreft, 250 km northwest of Agadez, Niger, in the Tiourarén
Formation (Tegama Group) by Albert-Félix de Lapparent in 1959.
(MNHN 1961–28, stored at Musée National d’Histoire Naturelle) is a series of vertebrae which was originally described as Elaphrosaurus gautieri
by de Lapparent in 1960.
A referred specimen (MNN TIG6), a complete, articulated series of vertebrae from the third neck (caudal) vertebrae to the sacrum (hip) with associated ribs, was discovered mingled with the remains of Jobaria
(a sauropod) and Afrovenator
(a basal tetanuran) at Tamerát, In Gall, Niger, by Paul Sereno in 1994.
