A blog written for those whose interests more or less match mine.

The mystery of tiny forelimbs (T. rex et al.)

with one comment

Very interesting. And the opening paragraph is classic:

For a dinosaur whose scientific name literally translates to tyrant lizard king,Tyrannosaurus rex gets a whole lot of shit for its hilariously puny arms. From the safety of their computer screens, and with the confidence that can come only from 66 million years of evolutionary separation, online artists have documented, time and again, all the things that this vicious predator probably couldn’t do—high five, apply sunscreen, put on a cardigan, do push-ups, etc.

By Alex Kasprak (and I’m going to be looking for that name) at Motherboard.

And, BTW, in the skeletal reconstruction of Gualicho shinyae, you can sort of see how that could become a chicken.

  1. I always believed that the arms shrank throughout evolution in favor of balance – a larger head. Rex and a lot of other theropods with short arms had ridiculously well developed and powerful skulls(especially Rex). I guess they just kind of stayed on the animals and were getting close to being dropped altogether, kind of an intermediary stage. The alvaeosaurs were even closer to dropping these arms – they had even shorter ones with only one finger. But I’ve heard that tyrannosaurids still had a lot of muscle in their arms…maybe for mating? Hell we will never know lol
