摘要

thalassochelydians是沿海对海洋适应的海龟的最早辐射之一,从侏罗纪到白垩纪时期。这项研究描述了Craspedochelys Renzi sp。 11月,来自哥伦比亚早期白垩纪早期的Hauterivian阶段的新的Thalashelydian,“ Plesiochelyid”龟。 It is the youngest and the only known record of “Plesiochelyidae’ outside Europe. The holotype, housed at the Naturhistorisches Museum Basel, was rediscovered after over 60 years and includes a partial shell, hindlimb bones, and caudal vertebrae. C. renzi shares key traits with “Plesiochelyidae”, including a V-shaped posterior plastral lobe lacking an anal notch; an在非植物上的凹痕接触,神经8和桥梁上的骨骼中的“中间”;该属的物种相对较短,而更广泛丰富我们对过去的生物多样性和乌龟的理解
