Why did dinosaurs have spikes on their back?

The most obvious theory is to defend themselves against predators. Spines and spikes like these occur much more commonly on plant-eating dinosaurs, which would have needed some way to protect themselves from meat-eating carnivores that might try to make them into a snack.

What did Stegosaurus have to protect them?

Tail spikes Stegosaurus defended itself by attacking its enemies with its spiked tail. Allosaurus bones have been found with holes made by Stegosaurus tail spikes.

What are the spikes on a Stegosaurus tail called?

A thagomizer (/ˈθæɡəmaɪzər/) is the distinctive arrangement of four spikes on the tails of stegosaurine dinosaurs. These spikes are believed to have been a defensive measure against predators.

Why does a Stegosaurus have plates?

The plates were a temperature-regulation device. If Stegosaurus was, in fact, cold-blooded (as most plant-eating dinosaurs of the Mesozoic Era presumably were), it might have used its plates to soak up light from the sun during the day and dissipate extra body heat at night.

What are the plates on a Stegosaurus for?

Today, it is generally agreed that their spiked tails were most likely used for defense against predators, while their plates may have been used primarily for display, and secondarily for thermoregulatory functions. Stegosaurus had a relatively low brain-to-body mass ratio.

What are the plates on a Stegosaurus called?

Its 17 plates, called scutes, were made of a bony material called osteoderms but were not solid; they had lattice-like structures and blood vessels throughout.

Which dinosaur has spikes on its head?

Every time you think you’ve seen it all some new, weird ceratopsian shows up. Dubbed the horniest dino in the world, Kosmoceratops boasted 15 horns and spikes on its head, including some on its forehead that curled downward like bangs.

Why did Stegosaurus have spikes on its back?

The Stegosaurus flaunted an array of plates and spikes. The spikes were probably used as defense mechanisms, while it is believed that the plates could have been the same, plus doubled up as a heat control feature. Stegosaurus was nearly the size of a bus and its unique anatomical features were never shared with the other stegosaurians.

What kind of dinosaur has spikes on its back?

Stegosaurus is one of the most easily recognizable dinosaurs, in part due to the plates and spikes on its back and tail.

What does the name Stegosaurus mean?

The name stegosaurus means “roofed lizard,” reflecting the belief of 19th-century paleontologists that this dinosaur’s plates lay flat along its back, like a form of armor.

What did the Stegosaurus eat?

Stegosaurus was an herbivore, eating only plants. Scientists have several theories about the purpose of the plates on Stegosaurus’ back. Perhaps they were for defense or to attract a mate. Perhaps the blood in the plates was warmed by the sun and then sent around the Stegosaurus’ body to keep the rest of the beast warm.
