A New Extinct Emydid Turtle from the Lower Pliocene of Oklahoma
"A New Extinct Emydid Turtle from the Lower Pliocene of Oklahoma" by Edwin C. Galbreath is a scientific publication produced in the late 1940s. This work contributes to the field of paleontology by documenting a newly discovered species of turtle from the Emydidae family, specifically a previously unnamed species of the genus "Chrysemys", found in the Lower Pliocene geological layers of Oklahoma. In this publication, Galbreath details the discovery of the fossilized remains of the turtle, named "Chrysemys limnodytes". The author provides a thorough description of the specimen, including dimensions and distinguishing characteristics such as the carapace and plastron structure. The work compares the new species with existing species, noting its unique features like the concave anterior end of the carapace and its broader form in relation to similar Recent turtles. Galbreath discusses the taxonomic significance of these findings and situates the turtle within the broader context of the Emydidae family, highlighting its evolutionary position and the limitations of fossil records in understanding relationships with modern species.
A New Species of Heteromyid Rodent from the Middle Oligocene of Northeast Colorado with Remarks on the Skull
"A New Species of Heteromyid Rodent from the Middle Oligocene of Northeast Colorado with Remarks on the Skull" by Edwin C. Galbreath is a scientific publication released in the late 1940s. This scholarly work focuses on a newly discovered species of Heteromyid rodent, "Heliscomys tenuiceps", from the Middle Oligocene era in Northeast Colorado. The document includes detailed descriptions and anatomical observations based on fossil evidence, significantly contributing to the understanding of Rodentia evolution during that period. The book provides an in-depth analysis of this new species based on the discovery of its skull and teeth, elaborating on its size, unique features, and anatomical specifics compared to contemporary species. The author discusses the skull's structure, including observations on the nasal, frontal, and lacrimal bones, and presents measurements of the skull and teeth that demonstrate the species' distinctive characteristics. The study ultimately sheds light on the evolutionary lineage of the Heteromyids and suggests that "H. tenuiceps" exhibits traits linking it to both earlier and later rodent forms, making it a significant find in paleontological studies.
Pliocene and Pleistocene Records of Fossil Turtles from Western Kansas and Oklahoma University of Kansas Publications Museum of Natural History Volume 1
"Pliocene and Pleistocene Records of Fossil Turtles from Western Kansas and Oklahoma" by Edwin C. Galbreath is a scientific publication written in the mid-20th century. This work presents a paleontological study focusing on the fossilized remains of turtle species discovered in Western Kansas and Oklahoma, specifically from the Pliocene and Pleistocene epochs. The book contributes to the understanding of turtle genera that existed during these geological periods, shedding light on their distribution and classification. The text details the examination of various turtle fossils collected from different sites in Kansas and Oklahoma, including fragments belonging to the families Kinosternidae, Emydidae, Testudinidae, Chelydridae, and Trionychidae. Each entry discusses the corresponding fossils’ average characteristics, associated geological ages, and the significance of these specimens in providing new insights into the evolutionary history and environmental adaptations of turtles. By describing findings such as the existence of large and small tortoise lines and unique fossil bone fragments, Galbreath emphasizes the importance of these records in enriching the fossil narrative of the region and advancing the field of vertebrate paleontology.
