VERIFY:period_end_mya: stored=89.8 suggested=86.3 confidence=high — Current literature places Megaraptor namunhuaiquii in the Portezuelo Formation, dated upper Turonian–lower Coniacian, with the taxon itself commonly listed as Coniacian; a stored end date of 89.8 Ma is exactly the Turonian–Coniacian boundary and therefore excludes the Coniacian part of its range, which should extend to at least the end of the Coniacian (~86.3 Ma).
