Welcome To Dinosaur Den

Dinosaurs ruled our earth for many, many millions of years. They are thought to be one of the most successful creatures that ever lived in terms of longevity and adaption. They evolved into many different shapes and sizes and had diverse modes of living.

	Some grew to magnificent sizes such as the more well known dinosaurs Brachiosaurus which measured 45 feet in height......
	and the Diplodocus at 50 feet high.
	However, recent research has suggested that the Sauroposeidon (which means Earthquake God Lizard) was a colossol 60 feet tall and weighed around 60 tons and was the largest dinosaur that ever walked the earth.

 

 

The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago) until they were wiped out by a massive comet that hit the earth, along with deteriorating environmental conditions. However, Dinosaurs are still around us today in many forms, and they are the birds who miraculously survived the blast all those years ago.

Dinosaurs are a specific subgroup of the archosaurs, a group that also includes crocodiles, pterosaurs, and birds. although pterosaurs are close relations, they are not true dinosaurs.
