The dinosaur of the day: Chirostenotes
- Oviraptorosaur that lived within the Late Cretaceous in what’s now Alberta, Canada
- Appeared just like Oviraptor, walked on two legs, had an extended 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
- Most likely 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 to use it to impale
- Sort species is Chirostenotes pergracilis
- First fossils present in 1914 by George Sternberg (pair of fingers)
- 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 had been later referred to Chirostenotes (consists of toes discovered, that had been initially considered Macrophalangia, decrease jaws considered Caenagnathus)
- Edwin Colbert and Dale Russell urged in 1969 that Chirostenotes and Macrophalangia had been synonymous
- Caenagnathus was discovered to be an oviraptorosaur (initially considered 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 had 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 urged 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 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 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 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 films began that also continues over 30 years later.
