In a unique tribute to their moms, two student scientists have named a newly identified amphibian species that lived long before the dinosaurs. The creature, discovered in a rich fossil site near present-day Chicago, offers fresh insights into early amphibian evolution.
- Frog-like amphibian lived over 300 million years ago
- Fossil found in Illinois’s famous Mazon Creek fossil beds
- Discovery honors the mothers of the student scientists
What happened
Two student interns at the Field Museum in Chicago, Allison Sefcovic and Payton Kohlberg, identified a new amphibian species that lived approximately 309 million years ago. This ancient creature, resembling a chubby salamander or frog, was found among fossil collections from the famous Mazon Creek area, known for fossil preservation that captures fine details like scales and eye impressions.
The new species was named Jeanerpeton mazonensis, meaning “Jean’s crawler from Mazon Creek,” in honor of both interns’ mothers, who share the name Jean. Originally mistaken for a more commonly known species, this fossil was re-examined and found to be distinct, allowing scientists to classify it as a new amphibian that expands understanding of early tetrapod biodiversity during the Carboniferous period.
Why it feels good
This discovery highlights the important role of young scientists and citizen collectors in paleontology, showing that fresh eyes and curiosity continue to unlock secrets of the prehistoric world. The painstaking study of fossils like Jeanerpeton helps fill gaps in evolutionary history, offering a glimpse of life before the dinosaurs and the roots of modern amphibians.
The beautiful preservation seen in the Mazon Creek fossils, where delicate features like belly ribs and even eye impressions remain, brings ancient creatures vividly back to life. Naming the species after their mothers also adds a heartfelt human touch to scientific progress, celebrating family and the support that inspires discovery.
What to enjoy or watch next
Keep an eye on ongoing research at the Field Museum’s Mann Lab and the Women in Science program, where students and scientists continue to explore and describe fossils from Mazon Creek and beyond. These efforts deepen our knowledge of Carboniferous ecosystems, home to giant insects and early land animals, and unearth more stories from Earth’s distant past.
