[D] Lapparentosaurus madagascariensis [sG] [T]
Describer
Bonaparte, 1986
Time
Jurassic Middle Bathonian
Classification
Saurischia Sauropodomorpha Sauropoda Brachiosauridae
Diet
Herbivore
Fossilsite
Isalo Formation, Majunga, Madagascar
Info
Genus - Typespecies
More then 4 partial skeletons lacking skulls,teeth.
The Middle Jurassic juvenile brachiosaurid material from Madagascar has been fully described in Ogier\\\'s thesis but remains unpublished, except for preliminary statements by Bonaparte, (1986). It appears that L. madagascariensis is very close to, if not the direct ancestor of, Brachiosaurus.
Rimblot-Baly, F., A. De Ricqles & L. Zylberberg (1995) looked at micro stuff on a growth series of this Mid-Jurassic sauropod. Typical in that growth rate was very high early on and slowed down later, the classic dino model now. They suggest the data strongly support sauropods as active land-dwellers with indeterminant growth and mass-related endothermy.
