The Early Cretaceous vertebrate locality Teete west of Yakutsk (Siberia) yields a diverse association of mostly terrestrial macro- and microvertebrates. Teete is one of the northernmost (palaeolatitude 63-65° N) occurrences of Mesozoic mammals worldwide and the only one of Early Cretaceous age from Asia. The Teete vertebrate assemblage bears a great potential for research on the palaeobiogeography and palaeoecology of Mesozoic polar vertebrates. The project aims at a complete recording of the vertebrate association, in order to gain information on the palaeoecology of Mesozoic polar ecostystems. At first hand questions of differing reactions of endothermic (dinosaurs, mammals) versus ectothermic (amphibians, squamates, choristoderes) vertebrates will be addressed. The project will also yield important new information on the palaeobiogeography of Mesozoic Asian vertebrates, which will be discussed with a wider background based on our previous projects in Central Asia (Kyrgyzstan: Balabansai Formation and Xinjiang: Shishugou Formation) as well as western Siberia (Berezovsk: Itat Formation). We expect ground-breaking new insights into the evolution and palaeoecology of Mesozoic Vertebrates in Asia.

早白垩世脊椎动物地区Teete西部雅库茨克（西伯利亚）产生了一个主要是陆地大型和微型脊椎动物的多样化协会。Teete是世界上中生代哺乳动物最北端（古纬度63-65°N）的发现之一，也是亚洲唯一的早白垩纪哺乳动物。在中生代极地脊椎动物古生物地理和古生态学研究中，tete脊椎动物组合具有很大的潜力。该项目旨在完整记录脊椎动物的组合，以获得中生代极地生态系统的古生态学信息。在第一手问题的不同反应的吸热（恐龙，哺乳动物）和变温（两栖动物，有鳞动物，脉管动物）脊椎动物将被解决。该项目还将获得关于亚洲中生代脊椎动物古生物地理学的重要新信息，并将在我们之前在中亚（吉尔吉斯斯坦：Balabansai组和新疆：石树沟组）和西伯利亚西部（别列佐夫斯克：Itat组）的项目的基础上进行更广泛的背景讨论。我们期待对亚洲中生代脊椎动物的进化和古生态学有突破性的新见解。
