Allosaurus (“Different Lizard”)

Lived: 150 - 155 million years ago in the late Jurassic period.

Size (average):  9.7 meters long and 2.3 metric tons.

About: 

The main predator in the late Jurassic period, the allosaurus’ teeth are large and serrated. So try not to get bit by this guy! The allosaurus also has light bones, which would explain how it can support its ginormous head that is packed full of teeth. The natural enemy of the allosaurus is gravity – if this fellow takes a spill, he’s not getting back up with tiny arms like that.

Pachycephalosaurus (“Thick-headed Lizard”)

Lived: The late Cretaceous period.

Size: 4.5 meters long and 450 kilograms.

About:

The pachycephalosaurus is a bonehead to say the least! The dome-shaped skull is 25 cm thick on top and despite its headbutting potential, it is speculated that in fact, the spine could not support this. Mysterious! This bipedal omnivore is definitely a badass dino with a small-dino complex.

Saurolophus (“Lizard Crest” or “Big Mouth” to any child born in and around the 80’s)

Lived: 69.5-68.5 million years ago in the late Cretaceous period.

Size: 9.8 meters long and 1.9 tons.

About:

The saurolophus is a duck-billed herbivore which could walk both bipedally or quadrapedally (multitalented!). No one is quite sure what the purpose of the crest on its head is, but I suspect it was very fashionable in the Alberta-region during that particular season. The most famous saurolophus is Ducky from the classic film, Land Before Time.

Iguanodon (“Iguana-tooth” or “The Fonzie of Dinosaurs”)

Lived: From the late Jurassic period to the late Cretaceous period.

Size: 10 meters long and 3 tons.

About:

This herbivore has conical spikes for thumbs causing it to have a perpetual state of thumbs up. Its tail is stiff, similar to that of a kangaroo, disproving the previous belief that the iguanodon was strictly bipedal. This dinosaur was probably everydino’s best bud.

Albertosaurus (“Alberta Lizard”)

Lived: The late Cretaceous period.

Size: 9 meters long and between 1.3 and 1.7 tons.

About:

Named for the province in which it was discovered, the albertosaurus is a carnivore a long the same lines as the tyrannosaurus rex, but much smaller. It has a large head with many teeth, and tiny arms with only two digits. If you’ve ever had to survive through an Alberta winter, you’d become extinct too! 

Dacentrurus (“Very Sharp Tail”)

Lived: The late Jurassic period.

Size: 8 meters long and weight is unknown to me.

About:

Among the largest of the stegosaur, this herbivore had a distinguishing double row of plates down its back and spikes on its tail. In fact, it was the first stegosaur ever discovered.

This dino-a-day fan melts my heart! I can tell we have a future paleontologist here. Or maybe a future pokemon trainer.
