原盖龟

原盖龟的P. gigas。

原盖龟(学名:Protostega)是一类已灭绝的海龟。牠们最初是于1871年肯萨斯州的斯莫基山组(Smoky Hill Chalk)发现,并由爱德华·德林克·科普(Edward Drinker Cope)命名。牠们长约3米,大小仅次于古巨龟,是已知第二大的龟。

原盖龟像现今的棱皮龟,其龟壳没有盾板,所以重量较轻及薄弱。原盖龟可能是吃水母及贝类等海洋生物。

Protostega skeletal reconstruction in the Rocky Mountain Dinosaur Resource Center, Woodland Park, Colorado

Protostega ('first roof') is an extinct genus of marine turtle containing a single species, Protostega gigas. Its fossil remains have been found in the Smoky Hill Chalk formation of western Kansas (Hesperornis zone, dated to 83.5 million years ago) and time-equivalent beds of the Mooreville Chalk Formation of Alabama. Fossil specimens of this species were first collected in 1871, and named by Edward Drinker Cope in 1872. With a length of 3 metres (9.8 ft), it is the second-largest sea turtle that ever lived, second only to the giant Archelon, and the third-largest turtle of all time behind Archelon and Stupendemys.
