The Majungasaurus or “Mahajanga lizard" is a genus of abelisaurid theropod dinosaurs that lived in modern-day Madagascar. It lived during the end of the Cretaceous Period, which was about 70 – 65 million years ago. Only 1 species of Majungasaurus’ have been identified thus far. The skull of a Majungasaurus The Majungasaurus was a bipedal

Deinonychus

This dinosaur lived during the early Cretaceous Period during the mid-Aptian to early Albian stages, which was about 115 – 108 million years ago. Its fossils have been found in Oklahoma, Wyoming, and Montana in

Lambeosaurus

Lambeosaurus, or “Lambe’s lizard" in plain English, is a genus of hadrosaurid dinosaur. This dinosaur lived in the Late Cretaceous Period in modern day North America, around 75 – 76 million years ago. This dinosaur is well known for its distinctive hollow cranial crest which sort of looks like a hatchet. The skeleton of a

Massospondylus

The Massospondylus was a prosauropod dinosaur from the Early Jurassic Period. It lived during the Hettangian to the Pliensbachian ages, which was about 200 – 183 million years ago. It was first scientifically described in 1854 by Sir Richard Owen from remains that were discovered in South Africa. It is one of the first dinosaurs

Compsognathus

The Compsognathus was a small therapod dinosaur that was the size of a turkey. It lived in the early Tithonian stage of the late Jurassic Period, which was about 150 million years ago. The Compsognathus lived in what is now known as Europe. Fossils have found 2 well-preserved fossils in Germany and France. Skeleton of

Deinosuchus

One of the extinct relatives of alligators are the Deinosuchus. The Deinosuchus lived during he Late Cretaceous period, which was about 80 to 73 million years ago.

Herrerasaurus

It is thought to be one of the earliest dinosaurs, because carbon dating has dated it back to the early Carnian age, which is the late Triassic Period which was around 228 million years ago.

Ambondro mahabo

The Ambondro mahabo is a mammal that lived during the middle Jurassic period (167 million years ago) in Madagascar. This species is known only from a fragmentary lower jaw skeleton that was first described by a team led by John Flynn in Nature, which was published in 1999.
