The article highlights five of the largest animals to have ever roamed Earth, including the blue whale, Argentinosaurus, Patagotitan, Megalodon, and Spinosaurus, with the blue whale still existing today as the largest animal, while the others are extinct relics of the past.
New research led by UChicago paleontologists challenges previous theories about the hunting habits of the sail-backed dinosaur Spinosaurus aegyptiacus, suggesting that it was a shoreline predator rather than an underwater hunter. The study reevaluates bone density calculations and statistical techniques used in previous research, concluding that Spinosaurus likely waded into waterways to ambush prey rather than diving deep. The findings shed light on the complexities of assessing the aquatic abilities of extinct species and highlight the importance of considering measurement errors and individual variations when analyzing bone density.
A recent study has raised doubts about previous research supporting the idea that Spinosaurus was a fully aquatic pursuit predator. The new study, led by University of Chicago’s Professor Paul Sereno and colleagues, critically assesses the methods of the prior research and identifies significant flaws, particularly in the statistical technique used. The findings emphasize the importance of using consistent and objective criteria when classifying behavior and taking measurement errors and individual variations into account when assessing bone density. The study challenges the notion that Spinosaurus was a deep diver and suggests that the dinosaur may have waded into waterways to ambush fish while keeping its toes anchored in the mud.
A new study on the Spinosaurus aegyptiacus, also known as the "heron from hell," suggests that the giant dinosaur likely hunted in shallow waters rather than diving deep for its prey. Researchers from the University of Chicago examined the bone density of the dinosaur and concluded that it wouldn't have been well-suited for diving. Instead, they believe the Spinosaurus ambushed fish in waterways while keeping its toes anchored in the mud, shedding light on the long-standing debate about its hunting behavior.
A new study challenges the idea that the Spinosaurus, a large carnivorous dinosaur, swam after its prey, instead suggesting that it waded and plucked its prey from the water. The debate among researchers centers on whether the dinosaur hunted from the shore, waded in the shallows, or swam in pursuit of its prey, with conflicting views on its swimming abilities. The latest research argues against the idea that Spinosaurus was a swimmer, citing bone density analysis and the dinosaur's body shape as evidence against its swimming capabilities.
A new analysis led by paleontologists from the University of Chicago reexamines the density of Spinosaurus bones to determine its aquatic behavior, challenging earlier suggestions that it pursued prey underwater. The study found major issues with the statistical technique used in a 2022 Nature study, highlighting the importance of consistent and objective criteria when assessing bone density and classifying behavior. The findings suggest that Spinosaurus was a wader, able to ambush fish in shallow waters, rather than a deep-diving predator.
Scientists in Spain have identified a new species of spinosaurus, named protathlitis cinctorrensis, that lived during the late Cretaceous period and walked on two legs. The researchers used phylogenetic analysis to better understand how species have evolved and concluded that it is a basal baryonychine, a subfamily of spinosaurids. The discovery of this new species in the same place as another type of spinosaurus means that the Iberian Peninsula was much more diverse than previously thought. The team believes that spinosaurids originated in western Europe during the Late Jurassic or Early Cretaceous period and then migrated to Africa and Asia.
Early fossils of spinosaurs, a group of unusual dinosaurs with elongated snouts and crocodile-like teeth, have been discovered in Morocco. The fossils date back to the Middle Jurassic period, around 168 million years ago, and suggest that spinosaurs were already a diverse and successful group of predators at this time. The discovery sheds new light on the evolution and ancient history of these fascinating creatures.
