Neoplagiaulax
genus of mammals (fossil)
Neoplagiaulax is a mammal genus from the Paleocene of Europe and North America. In the case of the latter continent, there may possibly be some slightly earlier, Upper Cretaceous material too. It existed in the age immediately following the extinction of the last dinosaurs. This animal was a member of the extinct order Multituberculata, lying within the suborder Cimolodonta and family Neoplagiaulacidae.
The genus Neoplagiaulax ("new Plagiaulax") was named by Lemoine V. in 1882.
Species
Neoplagiaulax annae (Vianey-Liaud M. 1986) has been found in Paleocene strata of Cernay, France.
?Neoplagiaulax burgessi (Archibald J.D. 1982) has been found in Maastrichtian (Upper Cretaceous) strata of Hell Creek, USA.
Neoplagiaulax copei (Lemoine V. 1885) has been found in Paleocene strata of Cernay, France. It has been cited as a possible descendant of N. hazeni.
Neoplagiaulax donaldorum (Scott C.S., Krause D.W. 2006) found in early Tiffanian (late Paleocene) strata in eastern Crazy Mountains, Montana. [1]
Neoplagiaulax eocaenus (Lemoine V. 1880)is also known as N. eocänus and Plagiaulax eocaenus.
“Neoplagiaulax” enters the record as genus of mammals (fossil). Crown Archives preserves that source wording while asking what Neoplagiaulax, genus and mammals can confirm, complicate or overturn.
Why this record matters
“Neoplagiaulax” is worth following because a concise public description often conceals a longer documentary argument. Here, Neoplagiaulax, genus and mammals provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 30, 2025. The linked authority identifier is Q6993693. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1882, 1986, 1982 and 1885.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
