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 reasonable paleoart that’s nonetheless influential over a century after it was drawn
Information:
- A brand new tiny relative of Hypsilophodon from Dinosaur Isle supply
- New silesaurs discovered that add to the talk about the place the group stands supply
Interview:
Charles Nye, a paleoartist, grad scholar at Oregon State College, and challenge lead for The Artemis Paleozoo, an artwork e book depicting the care and preservation of life that point forgot.

The dinosaur of the day: Gideonmantellia
- Basal ornithopod that lived within the Early Cretaceous in what’s now Teruel, Spain (Camarillas Formation)
- Seemed considerably much like Hypsilophodon
- Small, slender, had an extended tail, brief arms, walked on two legs, a considerably lengthy cranium with a beak
- Holotype skeleton estimated to be about 3.2 ft (1 m) lengthy
- Holotype is a partial articulated skeleton (no cranium) of a juvenile
- Unfused bones, so was an immature particular person, and a few of the lack of fusion means the animal was nonetheless rising when it died, so it’s laborious to know precisely how outdated it was (no histology performed)
- Holotype contains 21 tail vertebrae, and different vertebrae, elements of the ribs, elements of ossified tendons, a part of the pelvis, each legs, and plenty of the toes
- “Each femora are virtually fully preserved, particularly the left one”
- “Altogether, 104 stays from the vertebral sequence, left hip and the 2 hindlimbs have been recognized, all belonging to a single particular person. This makes it probably the most full ornithopod skeleton and one of the crucial full dinosaur skeletons present in Spain”
- José María Herrero Marzo and his son discovered the fossils in 1982
- First regarded as cf. Valdosaurus sp., primarily based on 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 realized it was a brand new dinosaur, after additional getting ready the bones, and he wrote about it in his thesis, and printed extra particulars and descriptions through the years
- Particulars within the pelvis and tail made it distinctive
- In 2006 he named the dinosaur Gideonmantellia amosanjuanae in his doctoral thesis, however the title wasn’t but legitimate (nomen ex dissertatione)
- Formally named in 2012 by Ruiz-Omeñaca and others
- Kind and solely species is Gideonmantellia amosanjuanae
- Genus title is in honor of Gideon Mantell
- Mantell was the “first creator to explain and to determine “hypsilophodontid” stays in 1849, as these of a really younger Iguanodon” (which later turned the paratype of Hypsilophodon)
- Mantell found dinosaurs together with Iguanodon, Hylaeosaurus, Pelorosaurus, and Regnosaurus
- Species title is in honor of Olga María Amo Sanjuán, “who was doing her thesis on eggshell fragments of vertebrates from the Decrease Cretaceous of Galve when she died prematurely in October 2002”
- Galve is a village within the Teruel province in Spain, and is thought 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 identical locality as Gideonmantellia had been elements of the toes of a medium-sized theropod, and fossils from bony fish, turtles, and crocodiles
- Locality the place it was discovered “was destroyed by the native clay-mining trade”
- After it died, the Gideonmantellia skeleton moved a brief distance and was buried shortly (no actual indicators of abrasion or weathering)
- Different dinosaurs that lived across the similar time and place included the spinosaur Camarillasaurus, Iguanodon, and plenty of indeterminate dinosaurs together with sauropods, dromaeosaurs, and allosaurs
- Different animals that lived across the similar time and place included turtles, snakes, crocodyliforms, pterosaurs, fish, and mammals
- Holotype of Gideonmantellia is on show in a neighborhood exhibition beneath municipal administration in Galve, Spain
Enjoyable Reality:
Charles Knight pioneered paleoart and formed a whole lot of what it’s right now, listening to particulars in anatomy and basing his work on actual fossils—together with for the now doubtful Agathaumas.
