Paleo Nerd is back baby! This is the first of a new series where I debunk common paleontological misconceptions, starting with something somewhat terror bird-related, Gastornis' status as a terror bird.

It's not just because the animal is herbivore, which doesn't mean it's not dangerous. For example, hippos, which are herbivores, kill more people than Lions, who are carnivores. So Gastornis may well have been extremely aggressive with other animals

Great to see you're back! You could always do the classics "T rex was a scavenger" and "Azdarchids couldn't fly", other topics could be "feathers initially evolved for flight", "mammals ONLY diversified after the KPg extinction", "Many theropods were strategic pack hunters similar to lions", and "ceratopsians initially evolved frills for fighting off predators". You could also do more general topics regarding how inaccurate weight estimates can be (especially when massive sauropods and/or fragmentary remains are concerned), issues with inferring the behaviour of animals from fossils, and that theropods and other extinct predators weren't killing machines/monsters but were instead just regular carnivores that experienced all the ups and downs modern carnivores go through throughout their lives.

@@thatonedinonerd9709 yupp T rex was an active hunter, but of course it did scavenge from time to time similar to modern carnivores. Everything I put in quotations is a misconception. Of course it is likely several theropods did hunt in packs, such as Mapusaurus and Albertasaurus as fossils of several individuals have been found together which probably indicates social behaviour. My point is that this isn’t evidence for well-planned strategic hunting that is shown in documentaries such as When Dinosaurs Roamed America and Dinosaur planet.

"Oxygen levels in the age of dinosaurs were much higher than today!" "(insert non-mammalian synapsid here) is a kind of reptile" "Pterosaurs were all fish-eaters that hunted by skimming the water's surface with their lower jaw." "Pterosaurs were *pterrible* at any form of locomotion other than gliding."

Not really. Both lineages appeared at around the same time, and Gastornis was never trying to mimic terror birds besides the very basic and reductive similarities of both of them being "big, flightless birds". If anything, Gastornis was a big-headed cassowary or a giant land parrot.

I'm kinda similar to how you're describing those who remember those three birds off the top of their heads when they think of Terror Birds, except in my case, replace Gastornis with Kelenken. Also, when I was growing up, I never knew anything about a bird called "Gastornis". The "giant bird that hunted primitive horse ancestors" when I was a kid was called "Diatryma". Then when I saw Walking With Beasts I heard about Gastornis for the first time, and only when I saw the behind the scenes featurette did I learn these two birds were actually the same creature.

Since Gastornis is a relative of waterfowl i think they could be opportunistic omnivores. Like, duck beaks appear to be specialized for eating seeds and soft algae of the lakes; but they can totally eat things like worms, arthropods, crustaceans, and even amphibians. Plus, many birds that are considered strict herbivores usually tend to eat meat; like how the Antipodes parakeets enters the burrows of grey-backed storm petrels to kill (and devour) the nesting adults. So i can totally imagine a Gastornis eating nuts and then feasting on a Propalaeotherium that got careless and got too close to it ;P

Hey Paleo Nerd, a wee question about Allosaurus; I keep hearing time and time again that Allosaurus was a species w/a weaker bite force than a lion, yet in one of your Jurassic Fight Club analysis videos, you said this was likely not the case as that measurement was made from Big Al 2, a juvenile allosaurus. However, given that the video of yours in question is dated to about 2 years ago, I just wanted to ask; is this still the case? Did Allosaurus have an extremely weak bite force given its size?
@PaleoNerd1905

I mean. It may not eat meat. (Although eggs may potentially be a different case. Lots of primarily herbivorous birds seem oddly keen on eggs for whatever reason) But. It’s also still a man sized bird with a beak entirely capable of cracking the average skull. Lookin at a cassowary. You don’t need to eat meat to be scary. I think it can still be called a “terror bird” even as a herbivore. We just need to remember that it’s not actually carnivorous.

Well, I can tell you right away that the reason Xenosmilus hodsonae is not associated with Titanis walleri is because the two predators might never have overlapped. Fossils of Xenosmilus are very rare as it is, but the first two specimens (which are well preserved) are believed to have come from the Irvingtonian (which dates from 1.8 mya to 250,000 ya), which came after the extinction of Titanis (which died out during the previous Blancan age). I have heard some sources claim that Xenosmilus first showed up in the late Blancan, but others do not support that, saying that it was strictly from the Irvingtonian. I’m not sure what the reason behind these contradictions is; could be that these older fossils are fragmentary, or their identification as Xenosmilus is dubious or the age of those fossils is uncertain, so you should look that up first. On the other hand, S. gracilis and Edward’s wolf, along with a whole host of other small to medium-sized predators, like the American Chasmaporthetes, early forms of Arctodus, Homotherium and Miracinonyx and late-surviving Borophagus are known from the lame localities as Titanis, so there’s little doubt that Titanis overlapped with these carnivorans. Also, don’t fall for the misconception that Titanis has been “downsized”, as some people will claim. This is not based on any recent study and is only being perpetuated by people who have randomly started emphasizing a 2005 study, which mentions its height as 1.5 meters (it’s pretty much just the “half-sail Dimetrodon” or “Droopy-Lipped Smilodon” thing all over again). But the known fossils of Titanis vary in size, which could suggest sexual dimorphism or age differences, and size estimates suggest a height range from 1.5 to 2 meters, and there is no reason to treat the higher estimates as invalid. Yes, Titanis certainly was not 3 meters tall, but nobody has taken that idea seriously in 15 years, and both Prehistoric Predators and Monsters Resurrected gave it a very accurate size and shape, down to giving it a robust build.
