大型龟化石——Manchurochelys
产地：亚洲，中国辽宁省
石板尺寸：23×18厘米
时代：晚侏罗世–早白垩世

这枚化石是来自中国西辽宁早白垩纪的原始龟Manchurochelys的完整骨架，距今约一亿二千年前。 

它展示了极为完整的骨骼结构：椭圆形背甲、清晰可见的椎骨与四肢骨，以及独特的长尾，与这一原始龟的形态特征完美再现。与现代龟不同，Manchurochelys的尾巴更长、四肢修长、爪子发达，显示出半水生的生活方式，既能在水中游动，也能灵活地在陆地上爬行。

作为中国西辽宁热河生物群的典型代表，Manchurochelys是研究龟类早期进化的关键物种，连接了更原始的龟类与现代形态之间的过渡。这块化石仍完整埋藏在周围的岩石中，具有清晰的骨纹理。

Large turtle fossil-Manchurochelys
Origin: Asia - Liaoning Province, China
Slate size: 23*18cm
Age: Late Jurassic-Early Cretaceous


This fossil is a complete skeleton of Manchurochelys, a primitive turtle from the Early Cretaceous of western Liaoning, China, dating back approximately 120 million years.

It preserves an exceptionally complete skeletal structure: an oval-shaped carapace, clearly visible vertebrae and limb bones, and a distinctive long tail, perfectly capturing the morphological features of this primitive turtle. Unlike modern turtles, Manchurochelys had a longer tail, slender limbs, and well-developed claws, indicating a semi-aquatic lifestyle that allowed it to swim in water as well as crawl flexibly on land.

As a typical representative of the Jehol Biota of western Liaoning, China, Manchurochelys is a key species for studying the early evolution of turtles, bridging the transition between more primitive turtles and modern forms. This fossil remains fully embedded in its surrounding rock, with clearly preserved bone textures.
