Z's Writing Assignment Science - Week 22

Today we are going to talk about how scientists find the genes of dinosaurs to find out what they look like. We are also going to talk about how the bones well, let’s just say how they get the way that they are today. Trust me. It’s not a pretty cycle. First, we’ll talk about genes and DNA. They are the stuff that tells you what you look like. Here’s an example of a DNA strip, A-N-A-N-A-N-G-G-Y-E-R-N-A-F-S-FS-s-u-R. As you can see, many letters repeat. A-N are mostly from the mom and there are more of them then that means the child is a girl and looks more like her mom. F-S is the dad. The child only looks a little bit like the dad. The rest are from grandparents, aunts and uncles. Then a little bit of it is her is own DNA. So, dinosaurs had these genes and when scientists found their bones, they could guess what they looked like.  Now we are going to look at how dinosaurs became bones. So, let’s say a stegosaurus had a fight with a tyrannosaurus-rex. He got wounded in the battle and ran away. He slowly dies from the wound. He dies. Raptures find the body and eat the insides. The hollow body gets pushed into the sea and everything but the bone gets washed away. The sea dries up and the body gets buried. The ground preserves the bones and the scientists find them and put them in museum.

This is the first I have heard of the dinosaur's extinction being caused by "rapture"! ;) Seriously, nice little piece of writing here!!!

LOL, I didn't catch that before! I think she meant "raptor", ROFL!
