Species

D. agilis Sereno, 1996 (type)

Deltadromeus (meaning "delta runner") is a genus of theropod dinosaur from Northern Africa. This carnivore had long, unusually slender hind limbs for its size, suggesting that it was a swift runner. It lived in the late Cretaceous Period, about 95 million years ago. It may have been one of the longest carnivorous dinosaurs, with one unpublished survey indicating that a referred partial specimen could represent an individual that was around 13.3 meters (44 ft) long, though it would have weighed only an estimated 3.5 tons, making it more slender than the giant carnosaurs. The more complete holotype specimen measured an estimated 8.1 m (26.5 ft) long.[1]

Deltadromeus skeletons have been found with those of the carnosaur Carcharodontosaurus, and it may have lived alongside the even larger Spinosaurus. The specific name D. agilis, meaning "swift delta runner", comes from the fact that this species had adaptations for running, and that its remains were found in a fossilized river delta. Deltadromeus was originally described as a large coelurosaur, but more recent studies suggest it was actually a ceratosaur, possibly a gigantic member of the noasaurid family.

Deltadromeus may be a junior synonym of Bahariasaurus.

Так вроде решили что коготь был на передних лапах? Или есть предположение что на задних как у рапторов? А быть может мегараптор из ноазаврид?

Абелизавроиды по-моему, они их родственники, но не из этого семейства.

Величина не преувеличена? Это как у т-рекса!

Это длина гиганотозавра! Тогда почему говорят что гига самый большой после спино?

В последнее время чаще говорят, что он был на передних конечностях и динозавр выглядел довольно обычно. Вообще действительно слабо верится, чтоб у цератозавровых появился коготь а-ля раптор.

Может предположение того, что коготь всё же был на передних конечностях связано со сравнением ноазавра с другими ноазавридами с Masiakasaurus например, у него такого когтя на ногах вроде не было и кости ног хорошо сохранились.

Oddly Angled Teeth Make Masiakasaurus Stick Out

By National Geographic News
(January 29, 2001)

It had a long neck and tail, walked on two feet, and weighed about as much as a German shepherd.

But the most unique feature of the newly discovered Masiakasaurus knopfleri is its teeth, some of which protruded from its jaw almost horizontally.


Scott Sampson, along with other paleontologists, discovered fossil evidence of this small carnivorous dinosaur on the island of Madagascar. “When we dug up the first lower jaw bone, we weren’t even sure it belonged to a dinosaur,” said Sampson.

The Masiakasaurus knopfleri’s lower front teeth are nearly horizontal, with the teeth angle increasing until the dinosaur’s fourth tooth, after which the teeth are vertical.

Although the back teeth of the dinosaur are similar to other predatory dinosaurs, their horizontal, conical front teeth “are otherwise unknown among other [predatory] dinosaurs,” according to the Masiakasaurus’ discoverers.

The dinosaur’s fossils were dated to the Late Cretaceous period (about 65-70 million years ago). They show a five- to six-foot (about two-meter) long dinosaur that weighed about 80 pounds (35 kilograms).

The name of the new dinosaur is derived from masiaka, the Malagasy word for “vicious” and sauros, which is Greek for “lizard.” Knopfleri honors musician Mark Knopfler, lead singer of Dire Straits. The scientists credit Knopfler’s music as a lucky charm; it seemed that many of their most important discoveries were made whenever they were listening to his songs.

“Finding fossils entails a heavy dose of serendipity,” said Sampson, “and we’ll take good luck any way we can get it.”

The excavation was funded in part by the National Geographic Society’s Committee on Research and Exploration.
