Named by
Casanovas Cladellas 1992
mediummedium: PBDB and Wikidata agree on who named it; Wikidata gives the year as 1993, one year apart, as when a work is dated one year and comes out the next.
Sources

Given by: Paleobiology Database. How it was chosen: PBDB leads.

Described in
M. L. Casanovas Cladellas (1992). Novedades en el registro fósil de dinosaurios del levante español [Developments in the fossil record of dinosaurs from the Spanish Levant]. Zubía 10: 139–151.
mediummedium: Only PBDB gives this; its author and year match the naming authority (Casanovas Cladellas 1992).
Sources

Given by: Paleobiology Database. The publication the Paleobiology Database gives as the authority for this genus name, usually the one that first named and described it.

Diet
herbivore (inferred for its group)
mediummedium: Only PBDB gives this, and it infers it for the whole of Ornithopoda, the group this genus belongs to, not from this genus's own fossils.
Sources

Given by: Paleobiology Database. How it was chosen: PBDB, inferred from a group the genus belongs to.

Way of life
ground dwelling, gregarious (inferred for its group)
lowlow: PBDB infers this way of life for the whole of Ornithischia; behaviour is rarely known for one genus.

Gaps are answers

What isn't known yet

  • Type species: no source we use gives it yet.
  • Order: no source we use gives it yet.
  • Common names: no source we use gives it yet.
  • What it was named after: no source we use gives it yet.
  • Held back: 1 fossil record left out: identified only tentatively (for example "cf.", "?" or the name in quotation marks).
  • Resting on one source: 4 facts come from a single source with nothing against them (rated medium): parent group (PBDB); family (PBDB); age (headline) (PBDB); diet (PBDB).

Size and appearance aren't covered yet, and diet and way of life only as PBDB infers them for the wider group. Omnisaura leaves the rest out rather than guess.

Where sources disagree

None open. Where our sources overlap, they agree on everything shown here.

Did it meet…?

?

Same time, different places. Their fossils overlap in age, 72.2 to 66 million years ago, but no rock formation holds both.
