The dinosaur of the day: Chirostenotes

  • Oviraptorosaur that lived within the Late Cretaceous in what’s now Alberta, Canada
  • Appeared much like Oviraptor, walked on two legs, had a protracted neck and tail, and a crest on the top
  • 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 massive feathers on the finger, which has been present in different oviraptorosaurs, it wouldn’t have the ability to 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 “slender handed”
  • Species identify means “all through gracile”
  • One other specimen discovered, that features a set of jaws with enamel, however later was renamed to Richardoestesia (a dromaeosaur)
  • Chirostenotes didn’t have enamel
  • Different fossils discovered that have been later referred to Chirostenotes (consists of ft discovered, that have been initially considered Macrophalangia, decrease jaws considered Caenagnathus)
  • Edwin Colbert and Dale Russell steered in 1969 that Chirostenotes and Macrophalangia have been synonymous
  • Caenagnathus was discovered to be an oviraptorosaur (initially considered a fowl), 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 fowl)
  • Russell and Currie steered 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 grew to become Leptorhynchos in 2013
  • However later research discovered Chirostenotes and Caenagnathus to be distinct from one another
  • Different dinosaurs that was thought-about to be Chirostenotes embrace Epichirostenotes and Anzu
  • Funston and Currie in 2019 described newly discovered Chirostenotes fossils, together with jaws, vertebrae, and elements 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 embrace ankylosaurs, ceratopsians, hadrosaurs, theropods
  • Different animals that lived across the similar time and place embrace amphibians, crocodilians, lizards, fish, plesiosaurs, mammals

Enjoyable Truth:

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