An Ornithopod Trio

[Logo7]

Three recently discovered ornithopods have been added to the family, but there isn't all that much information about any of them, so I decided to combine all three announcement posts here. The first, Pareisactus evrostos ("Robust intruder"), is a genus of rhabdodontid iguanodont from the Late Cretaceous of Spain. Its genus name originates from the fact that the bones that make up its holotype were the only iguanodontid bones found among a large group of hadrosaur bones, while its species name originates from the thickness of the bone. The second, Sektensaurus sanjuanboscoi ("Universidad Nacional de la Patagonia San Juan Bosco island lizard"), is a genus of elasmarian ornithopod from the Late Cretaceous of Argentina. It's genus name is a combination of the Tehuelche word "sekten," meaning "island," and the Greek "saurus," meaning "lizard," while its species name is a reference to the Universidad Nacional de la Patagonia San Juan Bosco, an institution which many of the authors describing the genus either worked at or earned a degree. The third, Mahuidacursor lipanglef ("Light arm mountain runner"), is also a genus of elasmarian ornithopod from the Late Cretaceous of Argentina. It's genus name is a combination of the Mapuche word "Mahuida," meaning "mountain," and the Latin "cursor," meaning "runner," while its species name is also a combination of the Mapuche words "Lipang," meaning "arm," and "lef," meaning "light." The only reconstructions I could find of these animals were made by DeviantArt artist cisiopurple. Here they are in addition to the papers describing the animals.

Here's your answer, right from the paper:

"Etymology: From the Greek παρείσακτος (pareísaktos), intruder. It refers to this species being known from a
single element found amidst hundreds of hadrosaurid bones"
