Overview
A new species of proto-amphibian has been identified from fossil deposits in the region surrounding Chicago. This discovery, made by student scientists affiliated with the Field Museum, dates the specimen to the Carboniferous period, approximately 309 million years ago. The species was formally named in recognition of the mothers of both student researchers, who share the name Jean.
Research Context
During the Carboniferous period, approximately 309 million years prior to the present, the geographical area now known as Chicago was characterized by a swampy river delta environment. This ecosystem supported a diverse array of life forms, including early land-dwelling animals, large insects, and various aquatic species. This specific location has since developed into a significant site for the recovery of Carboniferous period fossils.
Approach
The new proto-amphibian was described by two student scientists from the Field Museum. The process involved the examination and formal description of a newly discovered animal from the aforementioned fossil-rich location.
Findings
The research resulted in the description of a previously unknown species of proto-amphibian. This newly described animal contributes to the understanding of the fauna present in the Carboniferous period, specifically within the river delta ecosystem that once characterized the Chicago area. The species was named to honor the mothers of the two student scientists, both of whom are named Jean.
Why This Matters
The discovery and description of this new proto-amphibian species contributes to the paleontological record of the Carboniferous period. It adds to the documented biodiversity of early land-dwelling animals present in the swampy river delta environments of approximately 309 million years ago. Such findings help to characterize ancient ecosystems and the evolutionary trajectories of life forms during this geological era.
