This paper by Mark Witton and Darren Naish just came out a few hours ago:

Besides the self-explanatory title, there is this phrase that people should take notice:

Besides the self-explanatory title, there is this phrase that people should take notice:
"Hatzegopteryx, however, shows potential for tackling much larger prey items, perhaps even killing animals too large to ingest whole (modern azhdarchid analogues, such as storks, are capable of attacking large animals, and killing human children, with their azhdarchid-like beaks: see Witton & Naish (2015) for discussion). Hatzegopteryx is the largest terrestrial predator known in Maastrichtian eastern Europe by some margin (Witton & Naish, 2015): its size, robust anatomy, and the deficit of other large carnivores in well-sampled European deposits implies that it may have been an arch predator in its community."
Yep, a TERRESTRIAL RAPTORIAL PTEROSAUR.

must see this...Does Infighting Really Rule Out Cooperation?
Note: The below text is not to say pack hunting in theropods is a definite fact. It just means that it's far from unlikely even with recent studies. Do also note that sociability across a clade varies drastically, so just because one theropod species may have been pack hunters doesn't mean any of its relatives were. I doubt any dromaeosaur bar Deinonychus and some trackmakers ever hunted in groups. Most importantly, it DOES NOT mean that Tenontosaurus spent most of its time being attacked by Deinonychus!!!
You've heard this argument before; "the majority of theropod aggregations show evidence of infighting and even cannibalism, so they were
Thoughts on dromaeosaur killing claws
Let’s talk about that most famous of Mesozoic predatory equipment...
1: slashing weapon
This is the first suggested use of this claw, but I see this as the least likely. In the defence of this hypothesis, the idea this claw was rounded in cross-section actually goes against fossil evidence, which show lateral compression on this claw (meaning that 2005 study got the result wrong because they got the claw shape wrong). However, there are still reasons to think that this hypothesis is unlikely, chiefly because claws are hardly ever used as slashing weapons by predators. Big cats, raptors, mustelids, etc all use their claws to grapple an
Official masses for Morrison Legends Characters
Excluding Duchess (because Harpactognathus mass estimates were made in the days when we thought pterosaurs were anorexic), here are the official masses for the named characters in Morrison Legends. One of these characters hasn’t even been shown yet, but will be revealed in the next chapter.
The mass and growth stages of various individuals is a very plot-relevant detail (it determines who can breed, who will win, and who will get bigger and more threatening in the future), so take note.
Ductor: 1.8 tons (skeletally mature Allosaurus superadult)
Nivea: 1.5 tons (growing Allosaurus adult)
Rebellis: 1 ton (growing Allosaurus adult)

New story: the Future Is Wild fanfic
inspired by ~Pterosaur-Freak (https://www.deviantart.com/pterosaur-freak)'a TFIW expansions and a discussion I had with said deviant.
No, Morrison Legends is not dead, I am actually writing the next chapter for it at the moment. But this new idea is too cool to ignore....
There are many, MANY more species in a given ecosystem than those showcased inTFIW, and Pterosaur-Freak's concepts are some of the best I have seen. In a way this is a collaboration, as I will be using said concepts as well as my own ideas to fill in ecosystems in this fanfic.
But the main species will be canon.
TFIW stated that terrestrial Cephalopoda, specifically squibbons, would become the next species to

The scary thing is that the neck could withstand HUGE amounts of force.
Basically, the paper suggests if you put 200 kg on a Arambourginia's neck, it would die. If you put 1000 kg on a Hatz's neck, it will be just fine.
