Size : Estimated 15 meters long

Type of Dinosaur : Sauropod

Type Species : L.‭ ‬madagascariensis‭ (‬type‭)‬

When it Lived :
Mid Jurassic, 169-164 million years ago

Lapparentosaurus, a genus that includes sauropod dinosaurs from the Middle Jurassic, is known. Its fossils were discovered in Madagascar (Isalo III Formation). L. madagascariensis is the type species.

Richard Lydekker, an 1895 biologist, named B. madagascariensis, a new species. This was based on fossils discovered by Joseph Thomas Last in 1894 in Majunga Basin, layers of the Bathonian Formation. Jose Fernando Bonaparte created a new genus in 1986, despite no connection to the English form. Lapparentosaurus madagascariensis is the type species. Albert-Felix de Lapparent is the generic name. Bonaparte assigned a holotype, MAA 91–92. It consists of two neural arches. Referred material from more than three individuals, possibly as many as ten from different stages of growth, has shown that there is much more. These include vertebrae and limb components, but not skulls. It is not yet possible to give a complete description or diagnose the species. It should not be confused or misunderstood with?Bothriospondylus madagascariensis. This taxon is now called Vouivria.

According to age determination studies using growth rings counts, this sauropod needed 31-45 years for sexual maturity. It was also relatively quick-growing due to the large amount of fibrolamellar bones.
