I Know Dino Podcast: Fukuiraptor


    Episode 32 is all aboutFukuiraptor, a carnosaur first regarded as a raptor.

    On this episode, we talk about:

    • The dinosaur of the day: Fukuiraptor, whose identify means “Fukui thief”
    • Kind species is Fukiraptor kitadaniensis
    • Kind species was presumably a juvenile (round 4.2 m lengthy), (14 ft), 2m (6’6) tall
    • Present in Japan, lived within the Cretaceous
    • Though Fukiraptor is a carnosaur (like Allosaurus), at first it was regarded as a raptor as a result of when it was first discovered, one among its giant claws on its hand was regarded as the “killing claw” on its toe, just like different dromaeosaurs. However ultimately scientists decided that the claw belonged on its hand.
    • At first scientists thought the kind specimen was a juvenile, now they assume it could have been an grownup, since different specimens have since been present in the identical space, and a few have been juveniles that have been so much smaller
    • The idea is that Fukiraptor could have been small, or it could have been small at a younger age and would have grown a lot greater through the years, like tyrannosaurids (a more recent evaluation discovered it could be a tyrannosaurid)
    • Fukiraptor is probably the most full (and solely) theropod present in Japan, formally
    • Holotype is a partial skeleton (jaw fragments, enamel, vertebrae, bones from arms and hind limbs)
    • In 2000, Philip Currie (College of Alberta) and Yoichi Azume (Fukui Prefectural Dinosaur Museum) described Fukuiraptor in a paper
    • Among the enamel had blood grooves, which have been discovered on Fukuiraptor enamel however not different theropod enamel from the Kitadani quarry
    • Tooth have been just like different carnosaurs, and had small serrations
    • In comparison with herbivore fossils within the Kitadani quarry, Fukuiraptor bones have been widespread
    • As a result of there are extra theropods within the quarry (which is uncommon), there could have been “some uncommon circumstances concerned within the genesis of the positioning”, For instance as a result of so many juvenile Fukuiraptors have been discovered, it could have been close to a nesting web site (one other instance of a quarry with a number of carnivore bones is the Cleveland-Lloyd quarry, which has greater than 70 Allosaurus people and should have been a predator lure); different websites with a number of carnivores have been as a result of drought (all died directly) or they raised the likelihood that they hunted in packs. Nevertheless it’s unclear why there are such a lot of theropods in Kitadani Quarry
    • Can see Fukuiraptor as an animatronic dinosaur within the Fukui Prefectural Dinosaur Museum in Japan (together with 10 different animatronic dinosaurs)
    • Animatronic Fukuiraptor blinks and strikes its head, in addition to poses threateningly
    • Fukui Prefectural Dinosaur Museum opened in 2000
    • Admission is 1200 JPY (~$10 USD)
    • One of many largest dinosaur museums in Japan, positioned in Katsuyama Metropolis, Fukui Prefecture (middle of dinosaur analysis in Japan)
    • Museum has 4 flooring
    • Close to the Kitadani Quarry, giant excavation web site, presumably one of many largest dinosaur quarries on the planet
    • Excavation web site has bones, eggshell and footprints
    • Fukuiraptor is a megaraptoran neovenatorid allosaurid (however megaraptorans could also be tyrannosaurids), as of 2012 when Fernando Novas and colleagues
    • Megaraptora is a part of Neovenatoridae (based on 2010 and 2012 research), making neovenatorids one of many final kinds of allosaurids
    • Not less than one megaraptoran, Orkoraptor, lived on the finish of the Cretaceous
    • Neovenatoridae is a household of allosaurids. That they had quick, large shoulder blades
    • Enjoyable Reality: Trillions of eggs have been laid through the Mesozoic Period.
