How when we dig up a dinosaur bone do we know it comes from a young animal or a smaller example of a different species?  That s a question the Museum of Natural History of Los Angeles collection of T.rex helps answer.
Yesterday, Erin and I visited the new Dinosaur Hall, where for the first time fossilised skeletons of three complete Tyrannosaurs are brought together fleetwood travel trailers in california to illustrate the different stages in the animal s development.
Comparing the three, we see that Tyrannosaurs don t just scale up uniformly as they grow.  The eye sockets, for example, are more rounded in babies, changing to a keyhole shape in the adult.  The accompanying texts to the display explain how the relative length of the foot bone to the leg decreases from 70% to 50% from 2 to 17 yrs.
This was a bit of fun we got roped into: a Tyrannosaur puzzle no less.   The bones of the T.rex are taken off the frame, and it s up to us non-experts to put them back in the right place.   It s harder than you might think and it makes you think! (Shh that s the point).
