since nobody actually has an explanation yet I’ll give my extremely unqualified one (aka, I was sent a tiktok like 2 weeks ago)
Basically they saw big T-rexes and little ones. They assumed the little ones were babies, but now new evidence has shown that they might not be related and they’re just a similar looking dinosower
no idea what the third version is, the tiktok didn’t go over that one 🤷♀️
I’ll let someone else with more experience correct me lol
This makes a lot of sense. Taxonomists are tasked with a difficult job organizing fossils into species. Its why there’s like 7 definitions of species. Off the top of my head: shape (morphology), sex (interbreeding), genetics (differences in key genes) with the majority of them existing to categorize extinct species

Also evolution (common genetic pool) and ecology (common niche, environmental pressures and behaviour).
