How do you explain why they were so big compared to modern reptiles and birds? If modern reptiles are indeterminate growers then they would get that big if only they lived long enough.
I don't see any scientific reason why animals can't live indefinitely. They just don't and we don't understand why. And I am not speaking from ignorance. When you look at the theories of aging they don't paint a full picture.
Isn't gigantism a rare disorder? I don't imagine it would be a common feature - relatively speaking - across an entire species.
You think all dinosaur fossils are anomalies?
You're the one who's arguing that dinosaurs didn't naturally develop to be the size they were; that there must've been an anomalous genetic defect that caused them to grow so large. How am I arguing their bones as we've discovered them in the modern age aren't representative of the species as a whole? 😁
Telomeres
The mice they use to test new drugs on have artificially extended telomeres. This allows them to tolerate drugs much better than natural mice and gives better test results for the pharma companies. These genetically modified mice don't live forever. They all die of cancer. As far as I know they don't even have significantly longer lives.
Outside of the this sort of testing, which obviously would have an impact on longevity, length of remaining telomere chain seems to have some predictive ability as to how long organism will live. Not my field so predictive ability might vary from species to species.
