The dinosaur of the day: Leinkupal
- Diplodocinae sauropod that lived within the Early Cretaceous in what’s now Neuquén Province, Argentina (Bajada Colorada Formation)
- Like all diplodocids, had a protracted neck and whip-like tail, and hindlimbs that had been longer than forelimbs
- Herbivorous
- Estimated to be 30 ft (9 m) lengthy
- Weight is unknown, however bones had been delicate and lightweight and most of its physique was neck and tail, so in all probability not that heavy (probably weighed about the identical as an elephant)
- In among the information articles about it, known as “the littlest big” (probably the smallest diplodocid)
- Form of the vertebrae was distinct from different diplodocid vertebrae (together with having bony projections off either side of the vertebrae, a.okay.a. transverse processes)
- Some neural spines bifurcated
- Had a broad, muscular tail, which was in all probability sturdy and it in all probability had quite a lot of management over its tail
- Kind and solely species is Leinkupal laticauda
- Fossils had been discovered between 2010 and 2012
- Fossils had been broken by erosion and never a lot to see, however the crew didn’t discover another fossils, so that they dug out Leinkupal vertebrae, then noticed it was a brand new dinosaur
- Fossils had been disarticulated and located combined up with dicraeosaur fossils
- Named and described in 2014 by Pablo Gallina and others
- Genus identify means “vanishing household” in Mapudungun
- Refers back to the dinosaur being the youngest identified species of Diplodocidae
- Genus identify refers to the truth that diplodocids appeared to die out throughout the early Cretaceous
- Species identify means “extensive tail”, due to its broad caudal vertebrae
- Second confirmed diplodocid from Gondwana
- Solely identified diplodocid from South America and youngest and just one identified from the Cretaceous (to this point)
- Sebastián Apesteguía, one of many authors, mentioned in a Reuters article, “a diplodocid in South America is as unusual as discovering a T. rex in Patagonia”
- Till Leinkupal, scientists thought diplodocids went extinct by the tip of the Jurassic
- Diplodocids had solely been present in North America, Europe, and Africa
- Late arrival to South America in all probability as a result of diplodocids had been in Africa for the reason that Early to Center Jurassic
- Doable that the sister group Rebbachisauridae ecologically changed diplodocids (group rose within the early Late Cretaceous)
- Holotype is MMCH-Pv 63-1, a entrance tail vertebra
- Paratypes embody extra entrance tail vertebrae, a hind tail vertebra, a entrance dorsal vertebra, a entrance tail vertebra, and two vertebrae from the center of the tail (probably extra discovered, however not formally referred)
- First regarded as a sister taxon to Tornieria (diplodocid that lived within the Late Jurassic in what’s now Tanzania)
- 2015 phylogenetic evaluation of diplodocids discovered Leinkupal to be a sister taxon to Galeamopus (and mentioned Leinkupal was nonetheless a legitimate taxon as a result of it’s the one one present in South America and the one one which lived within the Cretaceous)
- Lived in a semiarid surroundings, south of a big desert
- Lived close to braided rivers
- Different animals that lived on the identical time and place included tetanurans, potential deinonychosaurians, and potential abelisauroids
Enjoyable Reality:
A brand new examine estimates that there have been a complete of about 2.5 billion T. rex all through Earth’s historical past (or in all probability between 140 million and 42 billion people).
