【摘要】 原始辽翼龙（Liaodactylus primus）为已知最早的具滤食性生态适应的翼龙，化石产自辽宁葫芦岛市建昌县，地层为晚侏罗世髫髻山组，年代距今约1亿6千万年前（161.8±0.4～159.5±0.6 Ma）。原始辽翼龙的发现记录了中国北方中生代燕辽生物群中翼龙类特异的食性，有助于了解该生物群中爬行动物的生态多样性。本文对应提供该化石种正型标本（PMOL-AP00031）的X光断层扫描（X-ray CT）数据集，包括CT原始图片数据、根据CT数据重建的上下颌三维模型及视频、以及用于系统分析的形态学矩阵。其头骨CT数据和形态学矩阵可应用于翼龙类形态、生态、系统发育的进一步研究。其翼龙取食器官的数字三维模型，3D打印为实体模型后可广泛应用于科研、教学和科普。更多还原

【Abstract】 Liaodactylus primus is the earliest filter-feeding pterosaur, discovered from the Late Jurassic Tiaojishan Formation in Jianchang County, Liaoning Province of China. It dates back to about 160 million years ago(161.8±0.4 – 159.5±0.6 Ma). The discovery of Liaodactylus primus documents a specialized feeding strategy among pterosaurs in the Mesozoic Yanliao Biota in northern China, which contributes to understanding ecological diversity in reptiles of the biota. Here we provide a dataset of the holotype of Liaodactylus primus(PMOL-AP00031) from X-ray Computed Tomography(X-ray CT), including original CT slice images, reconstructed three-dimensional CT models of the mandibles, animated videos, and morphological character matrix for phylogenetic analysis. Data for the skull of Liaodactylus primus based on CT scan will contribute to further studies of pterosaurs regarding their morphology, ecology, and phylogeny. Three-dimensional virtual models of the mandible of Liaodactylus primus can be 3 D printed, with broad applications in research, teaching, and public outreach.更多还原
