|Gorgosaurus at the Children's Museum, Indianapolis (USA).|
|The braincase of Gorgosaurus.|
|The circular region marks a break in the braincase, that shows the dark boney mass growing with the paler calcitic infill...|
could this be a bony tumour that had our dinosaur tripping over its own feet?
I heartily recommend that if you are within a thousand miles of Indianapolis....go to the Children's Museum! It is one of my most favourite museums anywhere on the planet...and I have visited a fair few splendid museums! If you join us at the Royal Society Summer Science Exhibition, you will get to see a tony potion of their world-class collections...for the very first time in the UK.
