1. It's not a shell.

2. It's how his spine looks.

Limestone

The spino had a crocodilian head. It was filled with inward-pointing canine teeth. The inward design was meant for keeping the prey from escaping its mouth.

Spinosaurus was anywhere from 15 meters to 18 meters long.

Spinosaurus fossils have been found in Morocco and Egypt, and they date to between 112 and 97 million years ago. This was during the Albian and Cenemonian stages of the Cretaceous period, which was the third and final period of the Mesozoic era.

Spinosaurus was larger than Tyrannosaurus, but they mostly hunted fish. Tyrannosaurus had a much greater bite force and regularly hunted large and dangerous prey like Edmontosaurus and Triceratops. They may have even lived in packs, which would give them a huge advantage. In a one on one fight, I would guess that either could kill the other, although in most combat between two species one will surrender before either die.

As a final note, Spinosaurus and Tyrannosaurus lived on separate continents millions of years apart, and thus they never would have encountered each other in life.

I don't think so, although they look it, they were slower than the T Rex w 11 mph top speed vs t-rex 18

The Spinosaurus could lay 3-5 eggs at a time

No Spinosaurus eggs or nests have ever been found. However, it is safe to say that Spinosaurus, like all other dinosaurs, would have hatched from a hard shelled egg, like a bird. Whether their parents took care of them or they were immediately independent is unknown.

Yes, at least, that's what its skull shape suggests. It was long and thin, like a crocodile. Crocodiles eat small animals and fish when food is scarce. So, it seems likely that Spinosaurus at small animals and fish. However, we only know Spinosaurus from a few incomplete skeletons, and the original specimens were annihilated when Germany was bombed, so we don't know to much about it. maybe it was powerful enough to hunt the larger sauropods in the area. We'll have to wait for more fossils to confirm the evidence.

Spinosaurus is thought to have survived primarily on fish, including giant coelacanths, sawfish, large lungfish and sharks, which lived in the dinosaur's river system, according to Ibrahim.

A couple of Spinosaurus's special adaptations include its enormous size, its specialized teeth and jaws, and its large sail. Spinosaurus were 49 feet long and weighed at least 4.4 to 10 tons, making them one of the largest meat eating dinosaurs ever and thus they were formidable to any other contemporary dinosaurs. Their long jaws filled with interlocking teeth were designed to be effective at catching the fish that swam in the swamps where Spinosaurus lived, making them one of the few known piscivorous, or fish eating, dinosaurs. Although the sail's use is unknown, it clearly was useful for something. Some guesses at the purpose of the sail include cooling the Spinosaurus on hot days, absorbing sun rays to warm the Spinosaurus, or as a display to attract mates or intimidate rivals.

NO. Alligators are not dinosaurs.

They are related though. Dinosaurs, Alligators and Crododiles belong to a group called archosauria.

The only descendants of dinosaurs alive today are birds.

The color of Spinosaurus, like other non-feathered dinosaurs, is completely unknown. However, by examining the feathers of some small dinosaurs under a microscope, paleontologists are beginning to piece together the colors of close relatives of birds. A few dinosaurs whose colors have been discovered include Anchiornis, Sinosauropteryx, and Confuciusornis.

Spinosaurus eat Fish, Pterosaurs and Other Dinosaur

Spinosaurus was a dinosaur that walked on two legs with three toed feet. They had two arms, each presumably with four fingers. Spinosaurus had a long, narrow head with non-serrated, interlocking teeth that were perfect for catching fish. To picture its head, imagine the head of a crocodile with a small crest over each eye. Spinosaurus was 49 feet long. The defining feature, however, was its many long, narrow spines that extended vertically from its back, and these spines were covered in skin, creating a large, semi-circular "sail" on its back. Some suggest, however, that rather than supporting a "sail," the spines supported a large hump.

The Spinosaurus was most closely related to other Spinosauridae, such as Baryonyx. The next largest group they belonged to was the Megalosauria, such as Megalosaurus, and then theropods, which include bipedal, lizard-hipped, and mostly carnivorous dinosaurs, ranging from Tyrannosaurus to Velociraptor. Today, the closest living relatives of Spinosaurus are the only surviving theropods, the birds. Ironically, even though non-avian dinosaurs died out, the birds have diversified into nearly 10,000 known species, making them the second most diverse group of vertebrates in the world today after the perciform fish.

Spinosaurus lived in North Africa from Morocco to Egypt between 112 and 97 million years ago. The climate there was tropical, and the landscape was a coastal tidal plain with mangrove swamps. Spinosaurus was adapted for a piscivorous, or fish eating, lifestyle because of its long, narrow jaws filled with narrow, interlocking teeth.

Carcharodontosaurus is a meat eater even larger than T-Rex, but smaller than Giganotosaurus. It is about 17 ft high, 43 ft long, and weighs about 7 1/2 tons. Their teeth are almost 7 inches long.

Spinosaurus was 49 feet long, making it slightly longer than 8 average American men laying on their backs, each with his head under the other's feet.

As for its height, Spinosaurus's legs are not fully known, but from reconstructions, one would guess that the height to the top of a Spinosaurus's head, 12 feet, was just more than twice that of the height of a man. In addition, the sail on a Spinosaurus went up an additional 4.5 feet, approximately, making the distance to the highest point on a Spinosaurus three times that of a man's height.

Spinosaurus is known only from incomplete skeletal remains, so determining its weight is difficult. Estimates range from 4.4 tons, or 55 times that of a healthy average man, up to 10 tons, or 125 times the weight of a man, all the way up to 18 tons, or 225 times the weight of a man.

ten feet, approximately

Yes, Spiosaurus had 1 natural enemy. It's name was Carcharodontosaurus. Note that note many bones of Carcharodontosaurus have been found. But from estimates it was close to the size of T-rex. It's skull has been found; and it was about 5 feet long! So when you compare this to a smaller scale preadator like Spinosaurus{12-14 feet tall, 39-40 feet long} Spinosaurus has a very small chance at living.

No nests or eggs of Spinosaurus have ever been found. Thus, it is impossible for us to know whether Spinosaurus even took care of its young at all. If they did, we definitely don't know how they took care of their young.

Spinosaurus's long, narrow snout, filled with conical, interlocking teeth, as well as evidence of possible pressure sensors for detecting fish they couldn't see in the water, all hint at fishing being their specialty. Additionally, partially digested fish scales were found in the stomach area of a Spinosaurus specimen, and oxygen isotopes suggest that they had a semiaquatic lifestyle. Thus, we can safely say that Spinosaurus was mostly piscivorous, or fish eating, but, like other large predators, they probably also scavenged opportunistically and hunted small land animals.
