About This Book

A scientific description documents a new heteromyid rodent species based on the anterior portion of a skull recovered from middle Oligocene silts in northeastern Colorado. The author details cranial and dental morphology—including a laterally compressed rostrum, nasal and premaxillary architecture, frontal and orbital bone relationships, and specific molar and premolar cusp patterns—provides a diagnostic comparison with living and fossil heteromyids and geomyids, and notes geological provenance and specimen cataloging. Plates and measurements accompany the osteological remarks to support the taxonomic conclusions.
