## Curiosity - Did you know?

Between 2022 and 2024, the biomechanics of this dinosaur sparked the decade's most heated paleontological debate. Initial studies argued that its dense, **pachyostotic bones** allowed it to swim submerged like a giant penguin. However, recent research in 2024 recalculated its hydrodynamics and buoyancy. These new models suggest the dinosaur was too unstable to actively pursue prey deep underwater. Instead, scientists now favor the "**super-heron**" wading hypothesis. This theory paints a picture of a predator hunting belly-deep along the riverbanks, using powerful neck muscles to launch lightning-fast strikes just beneath the water's surface!
