材料和方法2017年，PP Skutschas，R. Schellhorn和DD Vitenko。来自屏幕清洗的样品含有许多脊椎动物微化石，包括鱼类、蝾螈、海龟、christoderes、蜥蜴、恐龙、tritylodontids和哺乳动物的遗骸（Averianov等人，2018年）。使用180 kV X射线管进行扫描，分辨率为2.39 μm。|托姆|xs微计算机断层扫描（μCT）设备（GE Sensing & Inspection Technologies phoenix| X射线），其位于德国波恩的波恩大学地球科学研究所。扫描设置为80 kV和80 μA，快门速度为每次捕获500 ms。该仪器产生各向同性体素，单个图像大小为2024× 2024像素。使用Avizo 8（Thermo Fisher Scientific）进行分割。
MATERIALS AND METHODSPIN 5614/4 was recovered during screen-washing of 500 kg of fossiliferous matrix from the Teete locality in Yakutia, Russia, 545 km west of Yakutsk (Fig. 1), in 2017 by PP Skutschas, R. Schellhorn, and DD Vitenko. The sample from screenwashing contained numerous vertebrate microfossils, including remains of fishes, salamanders, turtles, choristoderes, lizards, dinosaurs, tritylodontids, and mammals (Averianov et al., 2018). The tooth was scanned with a resolution of 2.39 μm using the 180 kV X-ray tube of the v| tome| xs micro-computed tomography (μCT) device (GE Sensing & Inspection Technologies phoenix| xray) housed in the Institute for Geosciences, University of Bonn, Bonn, Germany. Scan settings were 80 kV and 80 μA with a shutter speed of 500 ms per capture. The instrument produced isotropic voxels, and the single image size is 2024× 2024 pixels. Avizo 8 (Thermo Fisher Scientific) was used for segmentation.
