Additional information / Summary

Plesiosaurier lebten von der späten Obertrias bis zum Ende der Kreide und sind zusammen mit den Dinosauriern ausgestorben.
Die (ehemalige) Ordnung wird mittlerweile (auch) als Klade geführt.

Detailed description

Plesiosaurier gehörten zu den Sauropterygia, sie werden in zwei auffällig verschiedene Taxa unterteilt:

  • die langhalsigen und kleinköpfigen eigentlichen Plesiosaurier (Plesiosauroidea)
    und die
  • Pliosaurier (Pliosauroidea), welche durch einen kurzen Hals und einen großen Kopf mit langer Schnauze charakterisiert sind.
