Paracoskinolina praereicheli, a Special Kind of Tiny Marine Creature, Found in Ancient Rocks in SE France, Franco-Swiss Jura, and Swiss Pre-Alps During the Dinosaur Era

Abstract

In this study, we report the discovery of a novel microorganism, Paracoskinolina praereicheli, a diminutive species reminiscent of prehistoric fauna. This organism was identified within ancient geological formations dating back to the era of dinosaur predominance. Specifically, its presence has been noted in sedimentary rock layers located in Southeastern France, the Franco-Swiss Jura, and the Swiss Prealps. Our research provides a detailed description of Paracoskinolina praereicheli, encompassing its morphological characteristics and ecological context. The temporal focus of this study spans the Late Hauterivian to the Early Barremian periods, offering insights into the biodiversity and environmental conditions of these epochs. This discovery contributes significantly to our understanding of microorganism evolution and paleoecology during a critical phase in Earth’s history.
