Woke up and chose violence this morning, so here goes:
Akshully, the Jurassic Park creatures are not reptiles for a number of reasons.
Reptile is paraphyletic and arbitrarily groups species regardless of their lineage.
T. Rex was likely warmblooded as its descendants are.
The creatures are not entirely dinosaurs. They’re hybrids of dinosaurs, and modern animals that the Jurassic Park scientists believed were most similar genetically.
Anyway, thanks for commenting, and I hope I’ve conveyed an appreciative and respectful tone. I sincerely just like sharing, learning, and discussing things.
don’t wanna fight, but i do want some clarification:
were they actually warm blooded, or that pseudo warm blooded thing some reptiles and fish do where they aren’t exactly warm ir cold blooded, but kinda in-between?
In all seriousness, thanks for bringing up that concept. On the surface, we generally group animals into endotherms and exotherms, but the reality is much more diverse, as you pointed out. Certain species of Tuna do make it into the category of endotherm because they generate enough heat internally to make a significant difference, however their body temperature is still largely variable depending on the surrounding environment making them also poikilotherms. Whereas mammals and birds are generally endotherms and homeotherms. I’m skipping over the concepts of hibernation and torpor in our bear and hummingbird friends, respectively, because that’s a whole other can of worms. In conclusion, I believe T. Rex, and many other dinosaurs, were both endotherms and homeotherms.
Thanks for adding perspective on this. I agree that it’s a much more diverse situation than just giant lizards running around. To add to this, I think it’s also likely that other theroppds were also warm-blooded in addition to T. Rex.
Very interesting. Were T-Rex really warm blooded, i thought that was a trait dinosaurs did not have at all and an advantage e.g. mammals had, allowing us to adapt better to the shifting climate?
You’re not spreading misinformation. You stated your thesis based on your assumptions. You tested it, and then shared your results. I really appreciate that.

Also, fight me.

Oh, you’re no fun anymore.

excellent, that was very helpful! thanks!
dinosaurs were all kinds of -blooded, but t-rex was probably fully warm blooded, like birds. Other, especially “older” ones were cold blooded.
thank you, that’s exactly what i wanted to know!

EDIT: birds even inherited warm bloodness from the dinosaurs: https://www.livescience.com/dinosaur-metabolism-warm-cold-blooded the more you know
