AI synopsis

What people are saying

Overall, the group shows moderate engagement with varied opinions, exemplified by comments referencing specific models, papers, and research tools, such as Henderson's work on floating postures and recent articles debating the aquatic nature of Spinosaurus. The tone balances scientific curiosity with ongoing debate, emphasizing the importance of data and interpretation over clear consensus.

AgreementNeither agree nor disagree

Discussions show mixed opinions, with some supporting the terrestrial interpretation and others advocating for the aquatic hypothesis, leading to a neutral overall agreement.

InterestModerate interest

Participants are relatively interested, with many referencing recent studies, models, and scientific papers, indicating engagement with current research.

EngagementModerate engagement

Comments include detailed references to models, papers, and debates about buoyancy and lifestyle, reflecting thoughtful engagement rather than dismissive reactions.

ImpactModerate impact

The discussions highlight active debate and the presentation of multiple pieces of evidence, suggesting a moderate influence on ongoing scientific discourse.

Abstract in brief

  • This study challenges the idea that Stromer 1915 was a semi-aquatic predator by using detailed 3D models to test its buoyancy and stability, showing it could float with its head above water but was prone to tipping over.
  • The models of other spinosaurids and related dinosaurs also demonstrated the ability to float in ways that would allow breathing, suggesting floating was not unique or specialized for a semi-aquatic lifestyle.
  • The findings indicate that despite adaptations like a hollow skeleton and air sacs, Stromer 1915 was still capable of walking on land, implying it may have lived near water and hunted in shallow environments but was fundamentally terrestrial.]

@sharkbitesteve It's this paper: https://t.co/rb7RxNTU1k, and here's Don's model of a floating Tyrannosaurus. Note that his programs predict the floating postures of crocs and birds just fine so, assuming the parameters of the dinosaur models are accurate, this is probably reasonable. https://t.co/llv8xdfrjX

Awesome display! Definitely looks cooler on fully aquatic interpretation, but I thought consensus emerging that it was a terrestrial wader: peerj.com/articles/5409/ palaeo-electronica.org/content/2021... elifesciences.org/articles/80092 Has there been new research pushing it back in other direction?
