Chicago's Field Museum on Friday unveiled a 46-foot cast of a Spinosaurus skeleton. The Spinosaurus is believed to be the largest predatory dinosaur to have existed.
Scientists have long struggled to interpret Spinosaurus fossils to determine the animal's behavior in life, uncertain whether it swam while hunting or simply waded into water in search of prey. Field Museum researcher Matteo Fabbri said the cast is about 60% of a skeleton, the most complete specimen of the species.
"Spinosaurus is a very weird animal," Fabbri said. "The proportions of the entire body are incredibly weird in comparison to any other dinosaur. The tail is extremely long, the legs are incredibly short, and the skull reminds (us) of the ones we find in modern crocodiles."
