Etymology
The name Halticosaurus comes from the Greek words altikos (αλτικος) meaning "good at jumping"/"nimble" and sauros (σαυρος) meaning "lizard"; thus "nimble lizard". Halticosaurus was described and named by Friedrich von Huene[3] in 1908 and the type species is Halticosaurus longotarsus.
Description
Halticosaurus longotarsus, is known from the
According to Welles (1984) H. longotarsus could be distinguished from the similar species
- the lower jaw is shallower and is pointed more in the front
- shorter and taller middle neck vertebraeare present
- a sharp keel is present on the bottom of the middle neck vertebrae
- the hip vertebrae are narrower
- lower third hip vertebra than in Liliensternus
- a more outwardly placed front trochanter
- the presence of smaller distal condyles on metatarsalII which extend less far proximally on shaft
In 1992, Michael Benton noted that the skull was 18 inches (46 cm) long but was lightly built, with large
However, the fossil material used by these previous researchers was later found to be mixed together with the remains of other animals, including a sauropodomorph (
Classification
In 1908, Huene originally assigned this genus broadly to Dinosauria, and after additional analysis in 1909 he assigned Halticosaurus to Saurischia.
A second species, based on a partial skull SMNS 12353b was assigned to this genus as cf. Halticosaurus orbitoangulatus in 1932.
A third species, H. liliensterni, was reclassified as Liliensternus by Welles.[8] Mortimer (2011) noted that between 1934 and 1984, Liliensternus was incorrectly considered to be a species of Halticosaurus.[12]
