Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests . They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were enormous.
The Oviraptoridae is further divided into the small, short-armed, and crestless subfamily Ingeniinae, and the larger, crested, long-armed Oviraptorinae. However, some phylogenetic studies have suggested that many traditional members of the Caenagnathidae were more closely related to the crested oviraptorids.
Oviraptor (/ ˈ oʊ v ɪ r æ p t ər /; lit. ' egg thief ') is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period. The first remains were collected from the Djadokhta Formation of Mongolia in 1923 during a paleontological expedition led by Roy Chapman Andrews, and in the following year the genus and type species Oviraptor philoceratops were named by Henry ...

In 2007, Xu and team assigned Gigantoraptor to the Oviraptoridae, in a basal (primitive) position. The anatomy of Gigantoraptor includes the diagnostic features of the Oviraptorosaurs . However, it also includes several features found in more derived eumaniraptoran dinosaurs, such as a forelimb/hindlimb ratio of 60%, a lack of expansion of the ...
They considered this specimen to be most similar and closely related to Oviraptor than to the other oviraptorids known at that time. [10] Despite being discovered in 1995, the specimen IGM 100/1004 remained partially figured and largely undescribed for years until its formal referral to the taxon Citipati osmolskae in 2018 by Norell and team.

When cats get injured or undergo surgery, the pain can last for some time. This can cause depression. Your vet may be able to help by adjusting pain medication, so always talk to them about it.
As one of the few oviparous pit vipers, D. acutus can lay up to 24 eggs, which may be retained during initial incubation, an adaptation that shortens post-deposition incubation time. However, it generally only deposits 11 or 12 eggs from June to August.
