Lapparentosaurus

名字的意思： “Lapparent's lizard”1

吃：植物長脖子恐龍侏羅紀中期

Lapparentosaurus was a huge, long-necked plant-eater that lived on the island of Madagascar during the Middle Jurassic. It walked on all fours and munched on leaves with its peg-like teeth. Scientists have found bones from several young and adult Lapparentosaurus, but no skulls yet.2 1

酷東西

趣味知識

Lapparentosaurus took 31 to 45 years to reach sexual maturity, based on growth rings in its bones.2

Its bones show a lot of fibrolamellar bone, which means it grew relatively fast.2

The first fossils were found before 1894 by Joseph Thomas Last in the Majunga Basin of Madagascar.2

The genus was named in 1986 by paleontologist José Bonaparte in honor of French geologist Albert-Félix de Lapparent.2 1

Lapparentosaurus has a mix of features from both early sauropods and more advanced titanosauriforms, which makes its family tree confusing.2

No skull of Lapparentosaurus has ever been found, so scientists have to guess what its head looked like.1

關於 Lapparentosaurus 最常被問的問題

?How big was Lapparentosaurus?

No one knows for sure because only partial skeletons have been found. It was a large sauropod, but scientists cannot give an exact length or weight.2 1

?What did Lapparentosaurus eat?

It was a herbivore, meaning it ate plants. It used its peg-like teeth to munch on leaves.1

?When did Lapparentosaurus live?

It lived during the Middle Jurassic, about 169 to 164 million years ago.1

?Where was Lapparentosaurus found?

Its fossils were found in Madagascar, in the Isalo III Formation of the Majunga Basin.2 1

發現: The first fossils were collected before 1894 by Joseph Thomas Last in Madagascar. In 1986, José Bonaparte named the new genus Lapparentosaurus after Albert-Félix de Lapparent, using two neural arches of dorsal vertebrae as the type specimen.2
仍有爭議: Scientists still debate whether Lapparentosaurus was a basal eusauropod or a more advanced titanosauriform, because its bones show a mix of traits.2
