(2008) and Carrano et al. (2012) assign this genus to Ceratosauria.
It is now believed that Limusaurus is its closest relative
(Wikipedia).
* Werner Janensch was a German paleontologist and museum curator
(the Natural History Museum of Berlin) who led an expedition (with
Edwin Hennig) to the Tendaguru Beds in Deutsch-Ostafrika, what is
now Tanzania, Africa. That expedition found many late Jurassic period
dinosaurs, including some Brachiosaurus. Janensch named
Dicraeosaurus (1914) and Elaphrosaurus (1920).
Nomina dubia (dubious names)
The following material was assigned to Elaphrosaurus over the
years, but further study revealed that these assignments were
dubious:
Elaphrosaurus iguidiensis, was described by Lapparent in 1960, and
the material was collected in Algeria, Libya and Niger in Early
Cretaceous sediments. The material consists of over 40 teeth, a
manual ungual, eight caudal vertebrae, a distal femur fragment,
and a complete tibia measuring 350 mm. These specimens
originated in three different localities and do not appear to belong
to the same species.
Elaphrosaurus gautieri, was first described by Lapparent in
1960, and the material was collected at the Tiouraren Formation in
Niger in Middle-Late Jurassic sediments. This material, a
complete neck vertebra, has since been renamed Spinostropheus
gautieri by Sereno et al. (2004).
