Glyptodontopelta
genus of reptiles (fossil)
Glyptodontopelta (meaning "Glyptodon shield") is a monospecific genus of nodosaurid dinosaur from New Mexico that lived during the Late Cretaceous (lower to upper Maastrichtian, 69 to 66 Ma) in what is now the Naashoibito member of the Ojo Alamo Formation. The type and only species, Glyptodontopelta mimus, is known from numerous specimens that consist of osteoderms, a dentary, supraorbital and bone fragments. It was named in 2000 by Tracy Ford. Edmontonia australis is a junior synonym of Glyptodontopelta.
Discovery and naming
Fossils of Glyptodontopelta, consisting only of bony armor, were found in the U.S. state of New Mexico. The type species, Glyptodontopelta mimus, was described by Tracy Lee Ford in 2000. The holotype, USNM 8610, consists of three pieces of fused flat osteoderms, found in the Campanian-Maastrichtian Ojo Alamo Formation. It was concluded to be a dubious name, a nomen dubium, in a 2004 review of the Ankylosauria, but a 2008 publication by Michael Burns concurred with Ford that its armor was distinctive enough to consider it valid. Burns also assigned Glyptodontopelta to Nodosauridae — rejecting Ford's Stegopeltinae — and proposed that another armored taxon from New Mexico, Edmontonia australis, is a synonym of Glyptodontopelta mimus, based on analysis of armor size and shape.
Most specimens referred to Glyptodontopelta comprise isolated osteoderms.
Begin with the source’s own compact description: “Glyptodontopelta” is genus of reptiles (fossil). The dossier treats that line as a proposition to test through Glyptodontopelta, genus and reptiles, not as a finished interpretation.
Why this record matters
The phrase “genus of reptiles (fossil)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 7, 2025. The linked authority identifier is Q522942. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000, 2004 and 2008.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
