How big is a Spinosaurus compared to a T-Rex?
Spinosaurus was probably a bit longer than T. rex, though it was more lightly built. But Spinosaurus lived 10-30 million years before T….Spinosaurus vs. T. rex.
| Spinosaurus | T. rex | |
|---|---|---|
| Length | 40-50 feet (12-15 m) | 33-45 feet (10-14 m) |
| Weight | 4-6 tons | 5-7 tons |
| Era | Middle Cretaceous | Late Cretaceous |
How large is a Spinosaurus?
Spinosaurus, which was longer and heavier than Tyrannosaurus, is the largest known carnivorous dinosaur. It possessed a skull 1.75 metres (roughly 6 feet) long, a body length of 14–18 metres (46–59 feet), and an estimated mass of 12,000–20,000 kg (13–22 tons).
What evolved into Spinosaurus?
Spinosaurus was a cross between T-Rex, a Great White Shark and a crocodile that had a paddle-like tail and a bony sail like structure on its back. Scientists have rewritten the textbooks with the discovery of the remains of the first “river monster” dinosaur.
How big is a Giganotosaurus?
41 feet long
First described in a 1995 study in the journal Nature, Giganotosaurus was, at the time, thought to be the largest carnivorous dinosaur. The specimen analyzed was up to 41 feet long (12.5 meters) from head to tail, and weighed between 6.6 and 8.8 tons (6 to 8 metric tons), the researchers estimated.
Was Spinosaurus bigger than Giganotosaurus?
Spinosaurus was the biggest of all the carnivorous dinosaurs, larger than Tyrannosaurus and Giganotosaurus. It lived during part of the Cretaceous period, about 112 million to 97 million years ago, roaming the swamps of North Africa.
Was Spinosaurus a good swimmer?
“Spinosaurus was probably a decent swimmer, and certainly a better swimmer than any other known large theropod [bipedal, mostly meat-eating dinosaurs],” study co-researcher Thomas Holtz, principal lecturer in vertebrate paleontology at the University of Maryland, told Live Science in an email.
How did the Spinosaurus go extinct?
The extinction of Spinosaurus would have been a different set of events than what killed the rest of the dinosaurs 65 million years ago. As its environment dried up during a change in climate, dwindling habitat would have reduced prey and increased competitive pressures among other large predators.
Is Giganotosaurus bigger than Spinosaurus?
More gigantic than Giganotosaurus Spinosaurus was larger than both T. rex and Giganotosaurus, which was previously the largest carnivorous dinosaur known. But it’s unclear just how big Spinosaurus was, due to incomplete fossils.
