Triceratops vs Tyrannosaurus - Difference and Comparison

Während Triceratops ein Pflanzenfresser war, war Tyrannosaurus Rex oder T. rex ein Raubtier. Beide Dinosaurier waren Zeitgenossen – sie lebten während der Kreidezeit in Nordamerika . In den Darstellungen der beiden Arten von Dinosauriern in der Populärkultur kämpfen sie häufig gegeneinander und gegen andere Dinosaurier wie Spinosaurus und Allosaurus .

Era

Triceratops lived in the Late Cretaceous period, around 68 to 65.5 million years ago.

T. Rexes lived in the upper Cretaceous Period, around 67 to 65.5 million years ago. They were two of the last species of dinosaurs to exist before mass extinction.

Anatomy

Triceratops was around 7.9 to 9 meters long, 3 meters tall, and weighed 6.1 – 12.0 tonnes. It had a large skull, one of the largest of all land animals , with a single horn on the snout, and a horn above each eye. The skull also had a large bony frill. It had short three-hoofed hands and four-hoofed feet. There has been some dispute over whether it walked with sprawling front legs, to support the weight of its head, or whether it had an upright stance.

T. Rex is one of the largest land carnivores that ever lived. The largest specimen found is 12.3 meters long and 4 meters tall at the hips. Estimates of its weight have varied from 4.5 tonnes to 7.2 tonnes. It had a short, muscular neck, a huge head, powerful legs, and two short forelimbs with two clawed fingers each. It also had a long, heavy tail to balance out its huge head and torso.

Feeding

Triceratops were herbivores. They probably ate low growing plants, although they may have been able to knock down taller plants to eat.

There is some debate over whether the T. Rex was a predator or purely a scavenger.

Discovery

The first specimen – a pair of brow horns – was discovered near Denver in 1887.

T. Rex teeth were first found in 1974 by Arthur Lakes in Colorado. The first partial skeleton was found by Barnum Brown in Wyoming in 1900. Brown found a second skeleton in Montana in 1902. T. Rex was named by Henry Fairfield Osborn, president of the American Museum of Natural History , in 1905. One T. Rex track has also been discovered. It was found in New Mexico in 1983.

Specimens

There is one complete Triceratops specimen, and many partial specimens are found each year. 47 complete or partial triceratops skulls were found in the Hell Creek Formation between 2000 and 2010.

The most complete T. Rex specimen contains approximately 85% of the original skeleton, and is named Sue after its discoverer, Sue Hendrickson. Sue was found in South Dakota in 1990 and now resides in the Field Museum of Natural History.

Lifespan

The average Tyrannosaurus lived to be approximately 30 years old, based on bone evidence provided in fossil remains.

The lifespan for Triceratops has not been accurately determined yet. One theory suggests that a Triceratop has a lifespan similar to that of mammals/ reptiles today, however, there is no scientific evidence to prove that Triceratops are warm or cold blooded .

Physiology

Tyrannosaurus are best described as large, bi-pedal, carnivorous theropod dinosaurs possessing powerful legs and torsos with numerous sharp teeth and tiny arms. There was a prior debate regarding sexual dimorphism in Tyrannosaurs, however this is now seen as geological dimorphism and not sexual.

Triceratops may also be described as large, two real horns on the skull and a shorter “horn” on its snout, looks similar to a rhinoceros /ancient bison , carnivorous theropod, possessing powerful short three-hoofed hands and four-hoofed feet and torsos with numerous sharp teeth. It was smaller than Tyrannosaurus, giving it increased mobility and speed .

Popular Culture

The main character of The Land Before Time movies was a triceratops. Triceratops also appeared in Jurassic Park and the BBC documentary Walking with Dinosaurs.

Since its discovery, T. Rex has been one of the most popular dinosaurs in popular culture . It first appeared in the 1918 movie The Ghost of Slumber Mountain, where it faced down Triceratops. The dinosaur appeared again in 1925 in an adaptation of Arthur Conan Doyle’s The Lost World, and in the 1933 movie King Kong. T. Rex also had an iconic appearance in the 1993 movie Jurassic Park, along with its sequels The Lost World and Jurassic Park III. The children’s TV character Barney is also based on the T. Rex.

Many books, movies and displays show triceratops and T-Rex in the middle of a dramatic showdown. They were first depicted in this way in 1942, when Charles R. Knight painted a mural of them fighting in the Field Museum of Natural history for the National Geographic Society.
