The dinosaur of the day: Lesothosaurus

Identify means “lizard from Lesotho”
Ornithischian that lived within the Jurassic in what’s now southern Africa (Lesotho)
Named by Peter Galton in 1978

Just one legitimate species: Lesothosaurus diagnosticus
Named for the nation Lesotho, the place it was discovered
Initially thought of to be an ornithopod, however Paul Sereno prompt it might be essentially the most primitive of recognized ornithischians

Had some primitive anatomy, like {a partially} closed gap in its pelvis by a medial wall (most dinosaurs didn’t have this)
Lesothosaurus has been generally confused with Fabrosaurus (an ornithischian from the identical time and place, that was named in 1964). However solely a jawbone and three enamel have been described of Fabrosaurus, so it’s onerous to know for certain)
Richard Butler mentioned in 2005 that Lesothosaurus was a basal member of Neornithischia (contains pachycephalosaurs, ceratopsians, ornithopods)

Is also an early thyreophoran (identical group as stegosaurs and ankylosaurs)
Richard Butler named a brand new dinosaur, Stormbergia dangershoeki, in 2005, and a few scientists assume it was an grownup model of Lesothosaurus, which might make them synonyms. (In 2017, Baron, Norman & Barrett studied the variations between the 2 and located they have been largely due to their progress.)
Bipedal

Had lengthy, slender legs, small arms (palms might probably not grasp issues), and a slender tail
In all probability was a quick runner
Had a beaklike construction

Beak was coated in keratinous materials
Had leaf-shaped enamel behind the beak, and 12 fanglike enamel in entrance of the higher jaws
Couldn’t chew its meals, however might slice it with its beak

Omnivorous, in all probability (primarily based on research of its tooth, which discovered not sufficient put on)
In all probability ate small animals and delicate vegetation
Might have been much like a gazelle, looking low-vegetation and operating off when predators approached

Might have lived in teams
In 2015, scientists CT scanned Lesotho skulls, which gave a way more detailed description of the cranium and was used to refer extra specimens to the genus.
These specimens have been buried collectively, which is why scientists assume they might have lived in teams

Enjoyable Truth:

Utilizing the time period “hen sized” to explain a dinosaur is problematic
