Tyrannosaurids and the M-shaped growth curve

Tyrannosaurids and the M-shaped growth curve

I'd like to start this post with a disclaimer. I am not a palaeontologist, I am a first year biology student with a laptop and (arguably too much) spare time. Take my words as such. To start off, what prompted this? Well I've wanted to write a post about some of my ideas on Tyrannosaurs, but none really warranted it yet imo. So what's new this time? SVP is just a few weeks behind us and one of the talks was on the remains of embryonic tyrannosaurids. The remains include a partial dentary from Judith River and a pedal ungual from the Horseshoe Canyon formation. The authors added a size estimate for the dentary, a skull of around 89mm (Funston et al, unpublished). This makes them some of the largest known hatchling dinosaurs. Now we've got a fair amount of immature Tyrannosaurid specimens by now, but none this young. The previous contenders are all already a few years old, but I noticed something interesting. Consider the diagram below of the holotype of Raptorex kriegsteini (LH PV 18),
