They served as both voracious predators and essential prey, supporting a complex web of life that included mosasaurs, plesiosaurs, and countless fish species. These geochemical fingerprints provide undeniable evidence of a global catastrophe coinciding with the mass extinction.
How Photosynthesis Collapse Unraveled the Marine Food Chain
This thin layer of sediment, found worldwide, is marked by an anomalously high concentration of the element iridium, which is rare on Earth's surface but common in asteroids. The stability of their world, however, was about to be shattered by a cataclysmic event that unfolded with terrifying speed.
Their sudden disappearance at the end of the Cretaceous period, alongside the non-avian dinosaurs, has long fascinated scientists and the public alike. The impact would have triggered an immediate and devastating blast of thermal radiation, igniting wildfires across continents.
How Photosynthesis Collapse Disrupted the Marine Food Chain
This layer also contains the mineral shocked quartz, which forms under the immense pressures of an impact, and glassy spherules created from molten rock flung into the air. Ammonites relied on calcification to build their intricate shells, a process highly sensitive to changes in ocean chemistry.
