名字的意思： “Narinda Bay lizard”1

吃：植物長脖子恐龍侏羅紀中期

Narindasaurus was a long-necked plant-eater that lived on the island of Madagascar about 168 million years ago. It had heart-shaped teeth that helped it munch on leaves. This dinosaur is known from just one partial skeleton, but it tells us a lot about how sauropods evolved.1 4

趣味知識

Narindasaurus was a turiasaur, a group of sauropods that lived mainly in Europe and Africa during the Jurassic.1

Its teeth are heart-shaped, which is a special feature of turiasaurs and helped scientists identify it.1

The only known fossil includes parts of the tail, leg bones, and a tooth, found in Madagascar between 1896 and 1905.1

Narindasaurus lived during the Bathonian stage of the Middle Jurassic, about 168 to 165 million years ago.2

Its tail bones have a unique asymmetrical pit that is not seen in other dinosaurs.1

The dinosaur was named in 2020, but the fossils were first described in 1907 as belonging to a different species.1

發現: The fossils were collected in Madagascar between 1896 and 1905 for the Muséum d'Histoire Naturelle in Paris. Armand Thevenin first described them in 1907, but the dinosaur was not named Narindasaurus thevenini until 2020 by Rafael Royo-Torres and colleagues.1
仍有爭議: Scientists are still unsure exactly how big Narindasaurus grew, because only a partial skeleton has been found.2
