Overview
- The species is formally described from a single skull found on Cape Breton Island, Nova Scotia, and dated to about 307 million years ago.
- High‑resolution micro‑CT of the closed jaw exposed an extra palatal tooth row and teeth on the coronoids with wear consistent with grinding tough plants.
- The research team interprets the animal as an early land vertebrate with herbivorous adaptations that revise views of when plant eating evolved.
- Only the skull is known, but comparisons suggest a stout body around 30 centimeters long, and the diet was likely omnivorous rather than strictly vegetarian.
- The fossil was discovered in 2023 by hobby paleontologist Brian Hebert, for whom the species is named, and the study appears in Nature Ecology & Evolution.
