賣家描述
Scientific name: Triceratops horridus, Marsh 1889 (ceratopsid three-horned Dinosaur) - Tooth
Location: Weston Co., Wyoming (USA). Private land.
Geological Formation: Lance Creek Formation
Age: Late Cretaceous, Maastrichtian stage (~68-66 Million Years)
Size: 1,2 x 1 cm
REF.: #J670
DESCRIPTION:
Outstanding nicely preserved tooth with nicely preserved enamel and well developed feeding wear.
Triceratops horridus from the Lance Formation refers to fossils of the iconic three-horned dinosaur found in the Late Cretaceous rocks of Wyoming and surrounding areas, often characterized by its longer snout and brow horns compared to T. prorsus, representing a common, earlier form in the dinosaur's evolutionary lineage before the later prorsus emerged just before the K-Pg extinction.
这些化石,包括牙齿、角和骨片,对于理解Triceratops的进化至关重要,horridus显示出如短鼻角和前向角向的眉角等特征,与其后代不同。
Key Information:
Triceratops horridus: Triceratops的两种已知物种之一,以其独特的“三角面孔”、草食性饮食和用于防御或展示的大型护盾而闻名。
Lance Formation (L Fm.): 美国西部的地质单元(怀俄明州、蒙大拿州、达科他州等),以丰富的晚白垩纪化石闻名,其中包括许多Triceratops标本,约66百万年前。
Physical Characteristics: T. horridus 通常具有更长的口鼻部和向前并略向外指的眉角,与T. prorsus不同,后者面部较短且眉角更直立。
Evolution: T. horridus 被认为是祖先种,线性进化成 T. prorsus,在非鸟类恐龙灭绝前夕。
Significance:
来自 Lance Fm. 的化石提供了Triceratops外观、行为(如进食、社交行为)及其最后进化阶段的关键证据。
总之,"Triceratops horridus Lance Fm" 描述的是在特定、富含化石层位的地质层中发现的经典Triceratops化石,代表属谱中的重要物种。
