Spinosaurus was also an enormous reptile similar to the T-Rex. It can be concluded that these dinosaurs dominated the earth in two different eras. The evolution of its structural features has assisted in revealing many facts about dinosaurs and their way of life. Habitat:įurthermore, the genetic makeup of the Spinosaurus’s nostrils and straight head reflected that it was a resident of shallow water. The spinosaurus teeth are also relatively tiny compared to the T-Rex teeth, interlocked between the upper and lower jaws like crocodiles. If the oral part of the Spinosaurus is analyzed, it reflects that the jaws have teeth but are not as sharp as the T-Rex’s teeth. The skull of the Spinosaurus is shiny but resembles the skull of a crocodile. However, its weight is possibly six tons, which is in fact, less than the average T-Rex. The Spinosaurus is claimed to be nearly 59 feet, which is a whole 20 feet longer than the length of the T-Rex. However, these have all been merely fragments in comparison to the fossil discovered in 1910. During the 1980s as well as in 2014, luckily, paleontologists found new specimens. Unfortunately, the fossil remains were demolished during World War 2. Spinosaurus was first unearthed during the 20th century, around 1910. Spinosaurus refers to ‘Spine Lizard’ for its substantial cruise-molded composition and spine on the back. The name Spinosaurus has been given to it due to its peculiar physique. More precisely, between the lower Albian to lower Cenomanian stages that occurred 112 million years ago. The Spinosaurus dwelled on our planet during the Cretaceous period. The Spinosaurus came to be known as the absolute largest carnivorous creature ever to roam on the face of the earth. Spinosaurus Largest Species Among Dinosaurs: These specimens have enabled them to know more about T-Rex than they do about the Spinosaurus. Some of them have also been mounted into skeletons that can be put on display. Present Specimens of The T-Rex:Īpproximately 30 specimens of the T-Rex lie with the paleontologists. The T-Rex used to be an enormous dinosaur that lurked around on earth for some 68 million years. The rumors ended when it was discovered that their hands were extremely strong and helpful during fights. These two tiny claws of the T-Rex were a mystery to be resolved by paleontologists. They were so small that they were assumed not to have had any real use or purpose for the T-Rex. What seemed odd in the physique of the whole gigantic creature, the T-Rex, which have puzzled scientist for years, is the hands that are extremely tiny compared to the rest of their gigantic bodies. Significance of T-Rex Teeth:įollowing research, it has been established that the T-Rex quickly tore off the flesh of its prey with its teeth, instantly consuming its freshly caught meal. The spines are sharp enough to penetrate the skin of a prey or predator. Their spine helped the dinosaur hunt their prey or a vicious enemy. The T-Rex’s spine has proved significant just as any dinosaur’s spine, it would be used for many purposes. The T-Rex dinosaurs were among the last species that lived before the mass extinction that ensued. The T-Rex dwelled on earth during the upper Cretaceous period, about 65-67 million years ago. Their jaws evolved to become one of the scariest and most deadly body parts that any creature walking our planet has ever possessed. Dangerous Animals:ĭue to their aggressive behavior in the movie Jurassic World, they scare not only kids but anyone who can grasp how enormous and lethal they were. The word Rex in the T-Rex means ‘king.’ Kids would hear stories about them from their parents and grandmothers for their dangerous appearance and lethal behavior. The T-Rex stems from the family of Tyrannosaurus.
