Spinosaurus was amongst the biggest predators ever to prowl the Earth and one of the most adjusted to water, however was it a marine citizen of the seas, diving deep to chase down its meals, or a semiaquatic wader that nabbed victim from the shallows close to shore?A new analysis led by paleontologists from the University of Chicago reexamines the density of its bones as a way of determining its life habits in water.Deep water swimmer or shoreline predator?When detailed descriptions of a nearly total specimen of Spinosaurus were very first published in Science in 2014, a UChicago-led research study team pitched it as a shoreline stalking or surface area swimming devil, not a completely marine undersea predator (check out more about the history of Spinosaurus and its preliminary discovery). Later on in 2020, a worldwide group of researchers countered that description with a study in Nature, utilizing its newly discovered, tall-spined tail bones to suggest that it moved itself like an eel to hunt underwater.A 2022 Nature study by many of those exact same authors validated their 2020 evaluation revealing that Spinosaurus had dense bones to use as ballast in diving like a penguin. Their outcomes, published in eLife, discovered that both types would have been unsteady when swimming at the surface area and far too resilient to dive and completely submerge.The Spinosaurus thigh bone (left) was thin sectioned with a diamond saw (middle) to expose under magnification its bone structure (right).”New estimations for ancient fossilsThe group started by asking new concerns about bone density, such as how to digitize thin areas, where to slice through the thigh and rib bones, and whether to consist of bones from more than one individual.Some modern-day marine mammals like manatees have inflamed, dense bones to help them remain underwater, like a scuba divers weight belt.
