Recent discoveries have elucidated many details of its anatomy, allowing for specialized studies focusing on its brain structure and forelimb function. ''Vollardisaurus'' was the largest theropod in its ecosystem and likely an apex predator which preyed on {{wpl|sauropods}}, {{wpl|ornithopods}}, and [[testudosaurs]]. | Recent discoveries have elucidated many details of its anatomy, allowing for specialized studies focusing on its brain structure and forelimb function.

The holotype and paratype of the ''Vollardisaurus'' were both discovered in the early 1840s and described at the same time in 1842, consisting of two partial skeletons and a piece of skull material from the [[Vollardic mountains]] in [[Yonderre]]. ''Vollardisaurus'' is the first theropod dinosaur to be described scientifically when [[Killian Lange]] described it in 1842. Two much more complete specimens were described by [[Thibault d'Avignon]] in the 1890s. The first is a partial skeleton, missing most of the skull, recovered from silver mines in the [[Vollardic mountains]] of [[Yonderre]] and currently part of the [[Collinebourg Natural History Museum]] collection. An even more complete skeleton was recovered from the [[Vollardic mountains]] the next year and is now housed at the [[Vollardie Paleontological Museum]] in [[Koop]]. This specimen is the largest and includes the only known complete skull and forelimb. | The holotype and paratype of the ''Vollardisaurus'' were both discovered in the early 1840s and described at the same time in 1842, consisting of two partial skeletons and a piece of skull material from the [[Vollardic mountains]] in [[Yonderre]].

The presence of ''Vollardisaurus'' in [[Caphiria]] was established in 1912 with the description of another partial skeleton. This specimen, consisting of parts of two vertebrae, partial pubic bones, a femur, a partial fibula, and fragments, represents a juvenile animal. It came from a bonebed in [[Iscasta]] and was found near the shoulder blade of a Sauroposeidon. An assortment of other fragmentary theropod remains from the formation may also belong to ''Vollardisaurus''. | |||
