TESTUDO THOMPSONI

The largest fossil turtle on the market
USA, South Dakota, White River Badlands
Oligocene (around 33 million years)
80 x 60 cm

Provenance: Swiss private collection

The term turtle is commonly used to describe both turtles and tortoises with the main difference being that turtles are aquatic; whereas tortoises are terrestrial, land-dwelling creatures. Anatomically, both have hard shells protecting their bodies. The top shell is called the carapace, and the bottom shell is called the plastron.

This colossal specimen is a male, as indicated by its pronounced "gular scute" (projection) extending from the front of the plastron, as well as the significant curvature of the underside of the shell. The scutes - the bony external plates - on the shell are in fine condition.
This turtle is, to our knowledge, the largest ever offered for sale. The size, combined with the minimal percentage of restoration, makes this a truly museum worthy fossil.

THOMPSONI海龟化石(TESTUDO THOMPSONI)

市场上最大的海龟化石!美国,南达科他州,白河荒地渐新世(3300万年)80 x 60 厘米
出处:瑞士私人收藏龟这个词一般用于水生和陆生龟,两者的主要区别在于龟是水生动物,而陆生龟是陆生动物。从解剖学上讲,两者都有一个硬壳,可以保护它们的身体。上层壳被称为甲壳,下层壳被称为腹壳。这个标本是一个雄性化石,这可以从其独特的从胸甲前端延伸出来的“棱盾”(鳞屑)和甲壳底部的明显弧度看出。甲壳上的鳞片--骨质外板--处于良好状态。据我们所知,这只海龟化石是有史以来最大的出售品。它的尺寸加上极少的修复工作,使它成为真正值得博物馆收藏的化石。
