Reptiles seem to have problems when aerobic activity comes into play. It is interesting to consider that dinosaurs may have had the best of both worlds, with the massive aerobic advantage of a bird-like respiratory system.

Like I said earlier most lizard cant breath and run at the same time so aerobic activity is not really an option. |

Looks like the debate reignited in carnivora and somebody contacted the researchers directly: Edit: Couldn't copy image link for some reason had to download and attach it. Attachments:

I actually contacted Dr. Seymour a while back too. The middle paragraph is pretty much what he told me. It's not that crocodiles and other ectothermic reptiles are literally physically weaker. It's that the energy needed to keep them working for a given time is much less.  |

^Nice to know but power not meaning strength damn miss leading.
The idea of ectotherms being inhernetly weaker always seemed absurd given that many of the animals with the most powerful jaws for their size and overall are ecotherms(crocodilians, piranhas.)

Always found it impressive how lizards are able to keep walking when a BOP when a large BOP is riding on their backs.

Kind of relevant, apparently the most recent research suggests that sebecids were actually ectotherms. Given that barinasuchus may have been the largest terrestrial predator on the planet since the dinosaurs that strongly discredits the idea that reptiles are weaker than endotherms. hal.sorbonne-universite.fr/hal-03329989/ |

Is there any way to tell the power and speed of non-avian dinosaur muscles in comparison to modern reptiles and mammals?I know that many muscle reconstructions are based on personal interpretation within a certain threshold of reality but i'm not sure the extent of which said interpretations vary and how they fare proportionally. If not dinosaurs, what about birds in general
