The systematic position of the Middle Jurassic sauropod Lapparentosaurus
madagascariensis is not fully understood due to a lack of useful anatomical
detail. Despite many new bone fragments from the axial skeleton,
post-cranial skeleton, and a hind limb having been previously unearthed,
its systematic position has not yet been satisfactorily established.
Although this Malagasy taxon is only recognised by two autapomorphies
located in the scapula and coracoid, two features of the neural spine,
which are reported here, provide additional information on the common
autapomorphies shared with the British genus Cetiosaurus. A full
description of the femur and neural spine helps to determine some aspects
of its relationship to other similar taxa. Remains of Lapparentosaurus
madagascariensis have been recovered from mixed facies that may have been
deposited in a shallow water lagoon during a transgressive period in the
Isallo IIIb subunit in the Majunga Basin.
