412 specimens | 20 OTUs | 11 genera | 2 families
This catalogue lists rodent museum voucher specimens of Sciuromorpha represented in the Alhajeri Lab photographic archive. All 412 specimens have skull photographs (crania and/or mandibles); 69 specimens also have study-skin photographs, including 68 skins photographed with a color reference. For most specimens, skull photographs include dorsal, ventral, and lateral views of the cranium together with labial and occlusal views of the mandible.
How to search: use the site search or your browser's Find function (Ctrl+F / Cmd+F) to search by scientific name, family, genus, museum abbreviation, or complete voucher identifier (for example, USNM 123456).
Photographic material: every voucher listed here has skull photographs. Vouchers under Skull + skin also have study-skin photographs. [CR] indicates that the skin was photographed with a color reference.
Complete dataset: The full specimen-level catalogue is available as a searchable Excel workbook, including taxonomy, museum and voucher identifiers, photographic material (skull only or skull + skin), and skin color-reference information.Â
Data note
Taxonomy: Taxonomic names were standardized against the Mammal Diversity Database (MDD), version 2.5, released 28 July 2026, where specimen-level assignment was unambiguous. Museum abbreviations and voucher identifiers follow the source records. This catalogue documents the lab's photographic archive and does not replace the holding collection's current catalogue or specimen determination. Researchers should confirm current taxonomy, identification, and specimen status with the holding collection before publication.Â
