Klastomycter
genus of extinct stem-reptile
Klastomycter (lit. 'broken nostril') is an extinct genus of acleistorhinid 'parareptile' known from the Early Permian (Artinskian age) Richards Spur locality of Oklahoma, United States. The genus contains a single species, Klastomycter conodentatus, known from a partial skull. The skull bones have a distinct pitted texture, like other acleistorhinids, many of which it coexisted with. In contrast to some of these relatives, which had large teeth of many different sizes, those of Klastomycter were small and all similar in size.
Discovery and naming
The Klastomycter fossil material was discovered at the Richards Spur locality of the Dolese Brothers Limestone Quarry in Comanche County, Oklahoma, United States. This fossil site consists of a complex system of vertical crevices that were filled in with sediment during the Early Permian, allowing organisms within to be preserved as fossils. The specimen is housed in the Burpee Museum of Natural History, where it is permanently accessioned as specimen BMRP2008.3.3. The specimen comprises much of an articulated skull, missing the mandible (lower jaw). To better observe this fossil and its internal anatomy, neutron tomography scans (a type of CT scan) were obtained using the Dingo instrument at the Australian Nuclear Science and Technology Organisation (ANSTO).
In 2026, Robert R. Reisz and colleagues described Klastomycter conodentatus as a new genus and species of acleistorhinid 'parareptile' based on these fossil remains, establishing BMRP2008.3.3 as the holotype specimen.
This brief starts where responsible research should: with the source description of “Klastomycter” as genus of extinct stem-reptile. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of extinct stem-reptile. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 May 17, 2026. The linked authority identifier is Q138919135. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.

Three-step research path
- Establish the record: confirm the title “Klastomycter”, its source revision and the description used here.
- Expand the search: follow Klastomycter primary sources, Klastomycter archive and Klastomycter research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
