Their population was severely diminished during the Permian–Triassic extinction event 252 million years ago, but Rhynchonellida became the most abundant brachiopod group during the Mesozoic. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis group is identifiable by their deep ribbed surfaces and short hinges, which usually come to a point. These bivalves were the first to evolve teeth sockets, which help to align the two halves as they close and make it harder for a predator to open the shell by twisting the valves. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIt is hypothesized that the radiating ribbed pattern helps regulate the flow of water in and out of the shell. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis fossil is millions of years old, but this order still exists today, albeit not nearly as abundant as they once were. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLocation: \u003c\/strong\u003eMorocco\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 1.4em;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eAge: \u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e~70 million years (Late Cretaceous) \u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e \u0026lt; 10g\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cem\u003ePlease note: This listing is for one brachiopod fossil.
