Study Uncovers Ancient Ammonites’ Immense Size as a Response to Predators’ Growth, Showcasing Remarkable Adaptation in Prehistoric Marine Ecosystems
A recent study reveals an intriguing aspect of evolutionary adaptation in prehistoric marine ecosystems, focusing on the immense size of ancient ammonites. Ammonites, extinct coil-shelled mollusks, exhibited a distinct frilled suture line. While most ammonites averaged half a meter in diameter, one species, Parapuzosia seppenradensis, stood out with diameters reaching 1.5 to 1.8 meters. The […]
