Interesting Facts About Baryonyx

Interesting Facts About Baryonyx Baryonyx is a relatively recent addition to the dinosaur bestiary, and one that (despite its popularity) is still poorly understood. Here are 10 facts you may or may not have known about Baryonyx. Discovered in 1983 Considering how well-known it is, its remarkable that Baryonyx was excavated only a few decades ago, well after the golden age of dinosaur discovery. This theropods type fossil was discovered in England by the amateur fossil hunter William Walker; the first thing he noticed was a single claw, which pointed the way to a near-complete skeleton buried nearby. Greek for "Heavy Claw" Not surprisingly, Baryonyx (pronounced bah-RYE-oh-nicks) was named in reference to that prominent clawwhich, however, had nothing to do with the prominent claws of another family of carnivorous dinosaurs, the Raptors. Rather than a raptor, Baryonyx was a type of theropod closely related to Spinosaurus and Carcharodontosaurus. Spent Its Day Hunting for Fish The snout of Baryonyx was unlike that of most theropod dinosaurs: long and narrow, with rows of studded teeth. This has led paleontologists to conclude that Baryonyx prowled the edges of lakes and rivers, plucking fish out of the water. (Want more proof? Fossilized remnants of the prehistoric fish Lepidotes have been found in Baryonyxs stomach!) Oversized Claws on Its Thumbs The piscivorous (fish-eating) diet of Baryonyx points to the function of the oversized claws this dinosaur was named after: rather than using these scary-looking appendages to disembowel herbivorous dinosaurs (like its raptor cousins), Baryonyx dipped its longer-than-usual arms in the water and speared passing, wriggling fish. Close Relative of Spinosaurus As mentioned above, the western European Baryonyx was closely related to three African dinosaursSuchomimus, Carcharodontosaurus and the truly enormous Spinosaurusas well as the South American Irritator. All of these theropods were distinguished by their narrow, crocodile-like snouts, though only Spinosaurus sported a sail along its backbone. Remains Have Been Found All Over Europe As so often happens in paleontology, the identification of Baryonyx in 1983 laid the groundwork for future fossil discoveries. Additional specimens of Baryonyx were later unearthed in Spain and Portugal, and this dinosaurs debut prompted the re-examination of a forgotten trove of fossils from England, yielding yet another specimen. Almost Twice as Many Teeth as T. Rex Granted, the teeth of Baryonyx werent nearly as impressive as those of its fellow theropod, Tyrannosaurus Rex. As small as they were, though, Baryonyxs choppers were much more numerous, 64 relatively small teeth embedded in its lower jaw and 32 relatively bigger ones in its upper jaw (compared to about 60 total for T. Rex). Jaws Angled to Keep Prey From Wriggling Free As any fisherman will tell you, catching a trout is the easy part; keeping it from wriggling out of your hands is much harder. Like other fish-eating animals (including some birds and crocodiles), the jaws of Baryonyx were shaped so as to minimize the possibility that its hard-won meal could wriggle out of its mouth and flop back into the water. Lived During the Early Cretaceous Period Baryonyx and its spinosaur cousins shared one important characteristic: They all lived during the early to middle Cretaceous period, about 110 to 100 million years ago, rather than the late Cretaceous, like most other discovered theropod dinosaurs. Its anyones guess as to why these long-snouted dinosaurs didnt survive up until the K/T Extinction event 65 million years ago. May One Day Be Renamed "Suchosaurus" Remember the day when Brontosaurus was suddenly renamed Apatosaurus? That same fate may yet befall Baryonyx. It turns out that an obscure dinosaur named Suchosaurus (crocodile lizard), discovered in the middle 19th century, may actually have been a specimen of Baryonyx; if this is confirmed, the name Suchosaurus would take precedence in the dinosaur record books.
