Surviving marine invertebrate groups include: articulate brachiopods (those with a hinge), which have undergone a slow decline in numbers since the P–Tr extinction; the Ceratitida order of ammonites; and crinoids ("sea lilies"), which very nearly became extinct but later became abundant and diverse.

Preživjeli morski beskralježnjaci uključuju brahiopode koji su opadali u brojevima od P–Tr izumiranja; amoniti; i krinoidi ("morski škorpioni"), koji su skoro izumrli ali su kasnije postali obilati i raznoliki.
