User blog:Blue The Raptor/Finding the age of dinosaurs

Because science blogs are the best blogs.

We're not really sure how long dinosaurs lived but I can explain.

First, we need to get a dinosaur (ex: Pelecamimus). The smaller, the easier as smaller dinosaurs lived shorter than big ones due to the bigger ones having less predators.

Now, dinosaurs lived from 80 to 300 years of age. We need to get examples from modern day animals like the dinosaur's closest ancestors, crocodiles and birds, if the dinosaur is armored then we can include shelled animals like turtles/tortoises.

So, the Pelecamimus had no armor so shelled animals are out of it. Salties can live up to 70 years of age but the pelecamimus is an omnivore, so the salties and nile crocodiles can be (ex)cluded. Pelecamimus' were similar to birds due to the feathers. Common Terns can live up to 19 years, so then we must add that up.

70+19= 89

So the pelecamimus might be able to live up to 89 years.

Using fossil bones
Man, you still have those fossil bones? Those things are prehistoric! Now, you need to count the marks, just like counting the rings on trees. For a tree, two rings signs one year of age. And the marks, the more marks, the older the computer animal is. For example, 200 rings on a tree means the tree is 200 years of age, but you also need to count the whorls if the tree species summons them when it ages.

So that's all.
