Just wanted to thank you for mentioning that many traditionally herbivorous animals do eat small animals and insects when they can get it. I think that it's important to remember that animals will opportunistically eat whatever they can digest at times. It always makes me wonder more about how transitions between dietary habits happen.

[@martinrosen9742]

Totaly agree! There are e.g. accounts of cows eating birds

[@JordanHayesRule]

Very true! I've seen a video of a horse that reached down and ate a baby chick once, scooped it up in one bite like it was nothin. Haven't slept all that well since.

You have no idea how right you actually are, since paleontologists believe therizinosaurs are more closely related to tyrannosaurs than other dinosaurs

[@noellecelnik4347]

That's a good observation, evolution is driven by niches, so it very well may have filled the opposite niche within the ecosystems it lived in - even being related to Trex subfamily. Therizinosaur was likely a main food source for a lot of predators, there was probably a lot of them judging from how often their fossils show up, and they seemed to be highly adaptive to their surroundings. These were some very cool and important creatures! :D

[@TheFaraway8]

what if they were claws used to tear up gigantic ant/ termite mounds, giant anteaters have similar claws that are no joke, for that purpose. idk just a thought

[@SoulDelSol]

Interesting theory. We often see big claws like that used for digging or hanging from branches. Have any dinosaurs been identified as insect eating? If not that would be highly unusual and therefore likely something missed or overlooked. You'd also expect dino to have long tongue or different mouth structure like other convergent ant eating animals - i would think the tongue is possible.

[@THEE.apples]

They're herbivorous

Therizinosaurs are my favourite group of dinosaurs, from way back when I knew them as Segnosaurs. They were so weird, and no-one knew where they fitted in, either in dino evolution, or ecologically. there was even speculation that they were specialised insect eaters, feeding on the early evolutions of social insects. Somehow, a thirty foot, multi tonne dino ant-eater had massive appeal for me!
