A research team led by the University of Zurich has announced the discovery of a nearly complete ichthyosaur skeleton in the high-altitude Graubünden region of the Swiss Alps. The specimen, dating back approximately 210 million years, belongs to a massive marine reptile estimated to have reached 20 meters in length, providing new insights into the size limits of Triassic marine life.
Dr. Elena Fischer, lead paleontologist on the project, noted that finding such a large marine fossil at an altitude of 2,800 meters is exceptional. The site reveals that these apex predators occupied a much wider range of ecological niches than previously believed, thriving in shallow coastal waters that were later pushed upward by tectonic activity during the formation of the Alpine range.
The preservation of the fossil's ribcage and vertebrae allows scientists to study the creature's lung capacity and swimming mechanics. Initial findings suggest this species possessed specialized cardiovascular adaptations that allowed it to dive deeper than contemporary reptiles, potentially rewriting the timeline for when marine species first conquered the deep ocean.
