    The dinosaur of the day: Chirostenotes

    • Oviraptorosaur that lived within the Late Cretaceous in what’s now Alberta, Canada
    • Regarded just like Oviraptor, walked on two legs, had a protracted neck and tail, and a crest on the pinnacle
    • Estimated to be round 8.2 to eight.5 ft (2.5 to 2.6 m) lengthy

    • Gregory Paul estimated it weighed 220 lb (100 kg)
    • Molina-Pérez and Larramendi estimated it weighed 88 lb (40 kg)
    • Had a beak

    • In all probability an omnivore or herbivore
    • Had lengthy, highly effective legs and slender toes
    • Chirostenotes had lengthy arms, slender, comparatively straight claws

    • Could have gone for soft-bodied prey and impaled and hook them with the second claw, which was unusually straight (grub, amphibians, reptiles, mammals)
    • However, if Chirostenotes had giant feathers on the finger, which has been present in different oviraptorosaurs, it wouldn’t be capable of use it to impale
    • Sort species is Chirostenotes pergracilis

    • First fossils present in 1914 by George Sternberg (pair of arms)
    • Lawrence Lambe studied the fossils however died earlier than naming them
    • Charles Whitney Gilmore named Chirostenotes in 1924 (identify got here from Lambe’s notes)

    • Genus identify means “slim handed”
    • Species identify means “all through gracile”
    • One other specimen discovered, that features a set of jaws with tooth, however later was renamed to Richardoestesia (a dromaeosaur)

    • Chirostenotes didn’t have tooth
    • Different fossils discovered that have been later referred to Chirostenotes (consists of ft discovered, that have been initially regarded as Macrophalangia, decrease jaws regarded as Caenagnathus)
    • Edwin Colbert and Dale Russell instructed in 1969 that Chirostenotes and Macrophalangia have been synonymous

    • Caenagnathus was discovered to be an oviraptorosaur (initially regarded as a hen), after the oviraptorid Elmisaurus was described by Osmólska in 1981 (present in Mongolia)
    • In 1988, Phil Currie and Dale Russell studied a specimen present in storage in 1923, which helped hyperlink all of the fossils discovered. They have been all thought-about to be Chirostenotes
    • In 1971, Joël Cracraft named a second species of Caenagnathus (nonetheless thought it was a hen)

    • Russell and Currie instructed this species was a extra gracile, smaller species, and named it a second species of Elmisaurus, as Elmisaurus elegans
    • Hans-Dieter Sues renamed Elmisaurus elegans to Chirostenotes elegans in 1997, however then it turned Leptorhynchos in 2013
    • However later research discovered Chirostenotes and Caenagnathus to be distinct from one another

    • Different dinosaurs that was once thought-about to be Chirostenotes embody Epichirostenotes and Anzu
    • Funston and Currie in 2019 described newly discovered Chirostenotes fossils, together with jaws, vertebrae, and components of the hindlimb
    • Bruce Rothschild and others in 2001 studied stress fractures in theropods and located that out of 17 Chirostenotes foot bones, just one had stress fractures

    • Different dinosaurs that lived across the similar time and place embody ankylosaurs, ceratopsians, hadrosaurs, theropods
    • Different animals that lived across the similar time and place embody amphibians, crocodilians, lizards, fish, plesiosaurs, mammals

    Enjoyable Truth:

    After the novel Jurassic Park was launched in 1990, a flood of dinosaur motion pictures began that also continues over 30 years later.
