Heptasteornis was no ornithomimid, troodontid, dromaeosaurid or owl: the first alvarezsaurid (Dinosauria: Theropoda) from Europe
Abstract
A distal tibiotarsus from the Upper Cretaceous of Sinpetru, Hateg Basin, Romania was originally described as belonging to the supposed pelecaniform bird Elopteryx but more recently various authors have proposed that it might belong to a non-maniraptoran tetanuran, ornithomimid, troodontid, dromaeosaurid or strigiform. None of these identifications withstand scrutiny. The recognition of a shared derived character and strong similarity of the specimen to the distal tibiotarsi of members of the Alvarezsauridae, a clade of controversial flightless maniraptoran theropods, leads us to suggest that it represents an alvarezsaurid. This is the first record of this group from Europe and has implications for their biogeography. The Elopteryx femora appear to belong to troodontids or pygostylians, and not to dromaeosaurids as recently argued

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
