A peculiar, 220-million-calendar year-old species of burrowing reptiles that evaded experts has been found, fossilized. A crew of Countrywide Park Assistance interns are credited with its discovery.
Concealed in a when-lively element of Arizona’s Petrified Forest Nationwide Park, the burgeoning paleontologists unearthed fossils of the Skybalonyx skapter, an “anteater-like reptile” that likely predates dinosaurs, in accordance to findings published this month in the Journal of Vertebrate Paleontology. It is a new species of a reptile formerly imagined to only stay in trees.
The unusual Skybalonyx skapter belongs to the group Drepanosaur, generally regarded the unsightly duckling of reptiles (potentially partly mainly because they bore some resemblance to fowl in daily life). The College of California Museum of Paleontology describes the creature’s functions as “seemingly drawn at random from evolution’s spare areas box,” with chicken-like beaks and tails punctuated with a claw, almost much too oddly fantastical to be real.
But the Skybalonyx skapter was genuine, and it lived in an space that was once overrun with everyday living during the Triassic Period some 220 million several years in the past, Xavier Jenkins, a Idaho Condition University PhD student who was credited with the Skybalonyx’s discovery, instructed CNN.
“It is truly so shocking that a web-site like Thunderstorm Ridge took this very long to be identified, and it is revealing a concealed diversity of historical existence at Petrified Forest,” Jenkins reported.

Jenkins’ colleague, Virginia Tech graduate pupil Ben Kligman, basically stumbled into the area, which they dubbed “Thunderstorm Ridge,” and discovered the smaller Skybalonyx fossils. In its prime, the region was very likely a “swamp-like” natural environment with rivers and lakes that attracted species of all sorts — such as, it appears to be, the ordinarily tree-dwelling drepanosaur.
The fossils Jenkins and his fellow interns identified were being so modest that they experienced to “screen-wash” them, that means they broke down the rocks with water as a result of metallic screens.
They named the species Skybalonyx skapter, which in Greek usually means “dung-claw digger.” It’s fitting since its bones had been “quite pretty much identified in a deposit of fossilized poop,” Jenkins mentioned, and its claws had been after fantastic for digging.
The team’s analysis showed that not like other drepanosaur species, which all share a big claw on their second finger, the Skybalonyx skapter’s claw was a great deal wider than those of other species. Other regarded drepanosaur species’ claws were being much extra suited for climbing and dwelling in trees.
Claws that huge, Jenkins said, are seen these days only in burrowing animals like echidnas, or spiny anteaters, and moles.
“Skybalonyx goes to clearly show that prehistoric ecosystems, these as those at Petrified Forest Countrywide Park, have been considerably more comparable to the modern day than earlier considered, with animals climbing, burrowing, swimming and traveling just like today,” Jenkins explained.
The discovery of Skybalonyx also implies that Petrified Forest hosted significantly more existence, and for considerably longer, than previous study expeditions counsel, Jenkins explained. The park’s swampy earlier also resembles ecosystems that survive today and host family of the drepanosaur.
“These prehistoric ecosystems are not as alien as once imagined, and are … eerily common in composition to individuals of nowadays,” Jenkins reported.
