Last week we put names into a hat and pulled one out to help us to name our big T Rex. The name we picked out was Rex! (Perfect for a T Rex!) Look out for Rex on our webpages, as he may pop up with a dinosaur related fact or a dinosaur activity for you to do! Today Rex would like you to learn a little bit about him. T Rex's are so big but they have very small arms! Rex has attached below a video from The Natural History Museum which tells you all about why T Rex's have tiny arms and how they used them.
