A quote from the Tinker website:
Nano teeth is interesting and is a great example of new things that Tinker
will be able to tell us…When Nanotyrannus was first discovered many scientists
insisted it was a young T-rex, not some midget distant cousin (Nano’s were
probably only half the size of a full sized rex). So much for that theory.
Tinker’s teeth are every bit T-rex, not at all like Nano teeth. We will be
learning many more things similar to this as more of Tinker is freed and
examined…and not just about Tinker. "
Hmmm... Nanotyrannus teeth in a Tyrannosaurus
nest - Wouldn't a more parsimonious sequence of events be that half-sized
Juvenile Tyrannosaurus rexes had baby teeth and sometime between then and
three-quarter sized development, the full adult teeth kick in? The site
even mentioned the fact that crocodile babies have needle teeth while the
adults do not, yet did not ultimately come to this conclusion. Is there
some piece of information about this new find that I've missed?
you are right on track. That WOULD seem to be a legitimate alternative
hypothesis. What we need now, of course, is the data to test these two
