Even T. rex struggled with midlife crisis
Fossil analysis shows many died in teens, just as they hit sexual prime

A major midlife crisis came early for dinosaurs in the tyrannosaur family, as new research suggests many of the giant beasts died just as they reached their sexual prime.
Like modern long-living birds and mammals, Tyrannosaurus rex and other tyrannosaur species experienced high mortality rates as infants and young adults, with just a choice few surviving to maturity.
Researchers recently investigated a quarry in the Canadian province of Alberta, where in 1910 several fossilized specimens were found of the species Albertosaurus sarcophagus, a member of the tyrannosaur family.
The collection of 22 dinos, which range from 6 to 30 feet long (2 to 9 meters long), remains the best evidence that tyrannosaurs were gregarious animals living in packs.
