Fact check
“The bones were found at the La Tejeria fossil site in Teruel, eastern Spain”
Reasoning
Four independent or primary sources state the bones were recovered at the La Tejería quarry in Teruel, while one peer‑reviewed study presents stratigraphic analysis suggesting they actually came from the nearby El Castellar locality. The presence of a reputable contradictory source prevents a definitive verification.
On confidence: Evidence is split between multiple supporting sources and a credible independent study that challenges the provenance, leading to moderate certainty about the dispute.
Important context
The contradictory source argues that geological and stratigraphic data place the fossils at El Castellar, not La Tejería, indicating an ongoing scholarly debate about the exact findspot.
