Top 28 Giant Prehistoric Animals

You should consider yourself lucky that these giant prehistoric animals are now extinct else there would have been no human civilization. Here are largest, scariest prehistoric animals ranging from prehistoric sea animals, prehistoric mammals and prehistoric birds.

If you are an active thinker then this list is going to raise a lot of questions. Before you jump on to the list we give you a common fact that our ancestors Homo Habilis (aka The first Human) walked the earth around 2.3 million years ago. Now you can compare the time line of prehistoric animals and human.

Most religions claims that God created all animals and human being. But science suggests that Human evolved on earth some 2.3 million years ago while Dinosaurs ruled the earth for more than 100 million years. So what god did during this time period? Why it took 100 million years for god to create intelligent life? A Second thought that comes to mind is that may be (and just may be) Human Being invaded this planet millions of years ago and wiped out all the dinosaurs to become the alpha animal of this planet. Phew, Too Much stuff. Anyways, Here are the 28 scariest giant Prehistoric animals:
