Throughout the discussions, some participants support the article's findings on forearm mobility with detailed mentions of joint rotation and wrist flexibility, using words like 'useful traits' and 'greater reach,' which show positive engagement. Conversely, others critique the research by referencing external studies or questioning methods, illustrating a mix of acceptance and skepticism that shapes the overall moderate scores.
AgreementNeither agree nor disagree
The discussions show mixed opinions; some support the conclusions about Australovenator's forearm mobility, while others challenge specific interpretations and cite conflicting studies.
InterestModerate interest
There is moderate interest among participants, especially those referencing detailed anatomical features and implications for hunting behavior.
EngagementModerate engagement
Posts reflect meaningful engagement through technical discussion, sharing of additional studies, and sketches, indicating participants are actively analyzing and debating the research.
ImpactModerate impact
The conversations highlight ongoing debates and interpretations, but overall they seem to have limited immediate impact on the broader scientific consensus.
Abstract in brief
The study examines the forearm and hand movement of Australovenator wintonensis, revealing a range of motion greater than some large theropods like Allosaurus and Tyrannosaurus, but similar to dromaeosaurs like Bambiraptor, suggesting specific hunting behaviors.
The forearm's joints allowed for unique movements including hyperextension of the claws, especially the first manual phalanx, indicating it likely used its hands and feet to subdue prey, with the first phalanx playing a key role in this process.
Overall, Australovenator’s forearm mobility shares similarities with both more primitive theropods and some modern bird-like carnivores, but its exact classification remains uncertain, highlighting its unique evolutionary position within megaraptorids.]

*sorta. The radius and ulna could rotate independently of one another at a certain flexion point for the whole arm, buuuut I wanted to sketch it with the conventional retro pose.

@VesuviusFloof15 @Tyrant_Lizerd Right? It's definitely up in the air, but here's the video I learned this from. It kinda contradicts Megaraptors and Tyrannosaurs being closely related, but I'm gonna ignore it and say they are related

@Gatorrrrrrrrr @aeroevo @DanPalaeon1 From what I can tell Megaraptorans like Australovenator have greater reach and arm ROM than other theropods. They also had greater wrist flexibility and extension capacity in their fingers then nearly any other taxa. All useful traits for restraining prey https://t.co/1ZFu2SnTDD
@ni075 実物を観察不能ゆえ分かりません。が↓論文では、前肢の可動域が広いとしている(そして鉤爪の断面は斬撃向き)ことから、少なくとも『鎌っぽい使われ方』をしていた可能性はあるかと

They also neglected to cite any study that conflicted with their assertions. I know because I sent them a forearm study from 2015 indicating the forelimbs of various theropods were far from useless in prey capture of holding.

They were stiffer than modern carnivoran limbs, because Carnosaurs weren't running on their hands. Stiffer limbs would help control an object they latched onto better because it means less movement offered to what they'd grabbed.
