Eoneophron infernalis Atkins-Weltman et al., 2024 (new genus and species)

(Tibiotarsus [fused shin and ankle bones] of Eoneophron infernalis, from Atkins-Weltman et al., 2024)

Meaning of name: Eoneophron = dawn [in Greek] Neophron [genus of the extant Egyptian vulture, sometimes called the "Pharaoh's chicken"]; infernalis = from Hell [in Latin]

Age: Late Cretaceous (Maastrichtian)

Where found: Hell Creek Formation, South Dakota, U.S.A.

How much is known: A partial right hindlimb.

Notes: Eoneophron was an oviraptorosaur, a group of bird-like theropods with short and often toothless skulls. The only other oviraptorosaur that had previously been named from the Hell Creek Formation was the much larger Anzu, which is estimated as having weighed between 200–350 kg. The type specimen of Eoneophron, on the other hand, is thought to have weighed around 78 kg. However, the microscopic structure of its bones indicates that it was close to fully grown when it died, suggesting that it is not a juvenile specimen of Anzu. Eoneophron is also unusual in that two of its ankle bones were fused to its tibia (shin bone); among oviraptorosaurs, this feature is otherwise known only in Avimimus from the Late Cretaceous of Central Asia.

New dinosaur just dropped

[taphonomenon]

"Leaping Hell Chickens"

The newly discovered Caenagnathid Oviraptor-line dinosaur called Eoneophron infernalis (Dawn Neophron of hell). This emu sized theropod lived in the upper Cretaceous Hell Creek formation in South Dakota.

It was described as a new species from remains that were previously attributed to another Caenagnathid species called Anzu wyliei. The paper that described it, Atkins-Weltman et al. 2024, recovered it as closely related not to Anzu but another Caenagnathid called Elmisaurus.

Caenagnathids are a family of distinct oviraptorosaurs with longer, lighter, toothless jaws and more slender, gracile anatomy than Ovoraptorids. Until the discovery of Anzu wyliei, remains of Caenagnathids were scarce and fragmentary, especially in North America. But then, in 2014, this giant North American Oviraptorosaur was described. Originally nicknamed the “chicken from hell”, Anzu was instead named after a fire-and-water-breathing bird monster from ancient Sumerian mythology. And, resembling a 3.5–3.75 meter (11.5–12.3 ft) long and 200–300 kilogram (440–660 lb) parrot with a high crescent-shaped crest on its head, Anzu certainly earned its name.

The oviraptorids were smaller and stockier than this tall giant, however, Anzu’s beak was not as heavily constructed as theirs. Like most ovoraptorosaurs, it was likely a herbivore or omnivore, using its beak to crack open hard shells and nuts. And, unlike its desert-dwelling cousins, it lived in lush forests and floodplains, likely with a different set of adaptations for this environment. Anzu’s large crest, the largest of all oviraptorosaurs, was actually quite thin and light, likely used for social signaling and to attrract mates.

Living in the North and South Dakota of the famous Late Cretaceous Hell Creek Formation, Anzu would have lived alongside many of the most familiar North American dinosaurs, including both species of Triceratops, Edmontosaurus annectens, and Tyrannosaurus rex. Aside from the Big Three, Anzu also lived alongside ankylosaurs like Denversaurus, pachycephalosaurs like Pachycephalosaurus, rarer ceratopsians like Torosaurus, and ornithopods like Thescelosaurus. Fellow theropods included Ornithomimus, Acheroraptor, Dakotaraptor, birds like Brodavis and Potamornis, and the slightly smaller caenagnathid Eoneophron. Azhdarchid fossils have been found here as well, possibly belonging to Quetzalcoatlus or a relative. Pseudosuchians lived here too, including Borealosuchus and Brachychampsa, as well as a large variety of turtles and mammals, at least one indeterminate mosasaur, and the choristodere Champsosaurus.

Sanatçının Eoneophron infernalis tasviri. — Atkins Weltman/PLOS OneBir derslik projesi için internetten fosil satın alan bir yüksek lisans talebesi, geç Kretase döneminde (100,5 milyon ila 66 milyon yıl ilkin) Dünya'da dolaşan, "firavunun cehennemden gelen şafak tavuğu" olarak malum, daha ilkin keşfedilmemiş bir dinozor buldu. "PLOS One" dergisinde 24 Ocak'ta gösterilen bir çalışmaya gore, Hell Creek Formasyonu'nun ortalama 65,5 milyon yıl öncesine tarihlenen Cenup Dakota bölümünden kaynaklandığı düşünülüyor. Oklahoma Eyalet Üniversitesi doktora talebesi Kyle Atkins-Weltman, araştırmanın baş yazarının şunları söylemiş oldu: Canlı Bilim 2020'de dört fosil için 5.000 dolar harcadığını zira ilk araştırma projelerinden birini bitirmek için gereksinim duyduğu kemikleri bulamadığını söylemiş oldu.Fosilleşmiş arka bacakların, cassowary'ye benzeyen ve "cehennemden gelen tavuk" olarak adlandırılan bir dinozor olan Anzu wyliei'ye ilişkin olduğu düşünülüyordu. Sadece Atkins-Weltman fosilleri taradıktan sonrasında bunların hemen hemen belirlenemeyen bir türe ilişkin bulunduğunu buldu."Kalbimin atışını hissettim" dedi. "Bu hakikaten kariyerimin bu kadar erken döneminde başıma mı geliyor?" diye düşündüm.Yeni türe, Atkins-Weltman tarafınca uzun müzakerelerin arkasından "Eoneophron infernalis" adı verildi. Eoneophron adı, Yunanca "şafak" anlamına gelen ve türün eski bulunduğunu belirten "eos" ile Mısır akbabalarının cins adı olan ve çoğu zaman "firavunun tavuğu" olarak malum "Neophron" kelimelerinin birleşiminden oluşur. "Firavun'un tavuğu"na meydana getirilen atıf, Atkins-Weltman'ın, Anzu wyliei tavuk lakabını kullanmanın yanı sıra, kısa süre ilkin ayrılan "Firavun" adlı evcil Nil ekran kertenkelesini onurlandırdığı anlamına geliyor. Otizmli Atkins-Weltman, "O benim hayatımın mühim bir parçasıydı" dedi. "O bir duygusal destek hayvanıydı ve bir bilim adamı olmanın, tüm stresle ve bunun getirmiş olduğu her şeyle baş etmenin en zor kısımlarını atlatmamda bana destek oldu."
