Episode 462: Designing a Paleozoo with Charles Nye. Plus a brand new hypsilophodontid from Dinosaur Isle, a brand new silesaur from Brazil, and the way Charles Knight made life like paleoart this is nonetheless influential over a century after it was once drawn
Information:
- A brand new tiny relative of Hypsilophodon from Dinosaur Isle supply
- New silesaurs discovered that upload to the talk about the place the crowd stands supply

The dinosaur of the day: Gideonmantellia
- Basal ornithopod that lived within the Early Cretaceous in what’s now Teruel, Spain (Camarillas Formation)
- Regarded quite very similar to Hypsilophodon
- Small, narrow, had an extended tail, brief fingers, walked on two legs, a quite lengthy cranium with a beak
- Holotype skeleton estimated to be about 3.2 feet (1 m) lengthy
- Holotype is a partial articulated skeleton (no cranium) of a juvenile
- Unfused bones, so was once an immature particular person, and one of the crucial loss of fusion approach the animal was once nonetheless rising when it died, so it’s exhausting to grasp precisely how previous it was once (no histology completed)
- Holotype contains 21 tail vertebrae, and different vertebrae, portions of the ribs, portions of ossified tendons, a part of the pelvis, each legs, and quite a lot of the toes
- “Each femora are virtually totally preserved, particularly the left one”
- “Altogether, 104 stays from the vertebral collection, left hip and the 2 hindlimbs were recognized, all belonging to a unmarried particular person. This makes it probably the most entire ornithopod skeleton and probably the most entire dinosaur skeletons present in Spain”
- José María Herrero Marzo and his son discovered the fossils in 1982
- First regarded as cf. Valdosaurus sp., in keeping with the femur (an iguanodont)
- In 1987 José Luis Sanz and others described the left femur and ilium (leg and a part of the pelvis), and referred it to Hypsilophodon foxii
- In 1994 and 1995, José Ignacio Ruiz-Omeñaca discovered it was once a brand new dinosaur, after additional getting ready the bones, and he wrote about it in his thesis, and revealed extra main points and outlines over time
- Main points within the pelvis and tail made it distinctive
- In 2006 he named the dinosaur Gideonmantellia amosanjuanae in his doctoral thesis, however the identify wasn’t but legitimate (nomen ex dissertatione)
- Formally named in 2012 by way of Ruiz-Omeñaca and others
- Sort and best species is Gideonmantellia amosanjuanae
- Genus identify is in honor of Gideon Mantell
- Mantell was once the “first creator to explain and to determine “hypsilophodontid” stays in 1849, as the ones of an overly younger Iguanodon” (which later become the paratype of Hypsilophodon)
- Mantell came upon dinosaurs together with Iguanodon, Hylaeosaurus, Pelorosaurus, and Regnosaurus
- Species identify is in honor of Olga María Amo Sanjuán, “who was once doing her thesis on eggshell fragments of vertebrates from the Decrease Cretaceous of Galve when she died in advance in October 2002”
- Galve is a village within the Teruel province in Spain, and is understood for the Newest Jurassic-Early Cretaceous vertebrate fossils (greater than 50 localities with fossils from dinosaurs, pterosaurs, sharks, amphibians, fish, turtles, crocodilians, mammals, and squamates)
- Additionally present in the similar locality as Gideonmantellia had been portions of the toes of a medium-sized theropod, and fossils from bony fish, turtles, and crocodiles
- Locality the place it was once discovered “was once destroyed by way of the native clay-mining business”
- After it died, the Gideonmantellia skeleton moved a brief distance and was once buried briefly (no actual indicators of erosion or weathering)
- Different dinosaurs that lived round the similar time and position integrated the spinosaur Camarillasaurus, Iguanodon, and quite a lot of indeterminate dinosaurs together with sauropods, dromaeosaurs, and allosaurs
- Different animals that lived round the similar time and position integrated turtles, snakes, crocodyliforms, pterosaurs, fish, and mammals
- Holotype of Gideonmantellia is on show in an area exhibition below municipal control in Galve, Spain
A laugh Truth:
Charles Knight pioneered paleoart and formed a large number of what it’s as of late, being attentive to main points in anatomy and basing his art work on actual fossils—together with for the now doubtful Agathaumas.
