Image stack, PLY-files and a NEX-file accompanying: A new symmoriiform from the Late Devonian of Morocco: novel jaw function in ancient sharks

We describe the small chondrichthyan Ferromirum oukherbouchi n.gen. et sp. from the Famennian (Late Devonian) of the Maïder region in Morocco. This chondrichthyan is exceptionally well preserved and displays not only mineralized soft tissues but also undeformed cartilages of the head, gills, and shoulder girdle. A reconstruction of the head using 3D-prints revealed a previously unknown kind of jaw articulation. Here, we make the original cropped image stack and PLY-files of the single cartilaginous elements accessible. Additionally, a nexus-file with the character matrix used for the cladogram shown in the article is included.
, Most of this text is copied from the article: The holotype of Ferromirum oukherbouchi n.gen. et sp. was scanned using an industrial computed tomography scanner (Nikon XT H 225 ST) at the University of Zurich, Switzerland. Data acquisition and image reconstruction parameters are: 224 kV, 474µA; filter: 4 mm of copper; isotropic voxel dimensions of 0.091 mm; 16-bit TIFF images were acquired; XX 8-bit TIFF images were used for reconstruction. Images were analysed and 3D models reconstructed using Mimics v.17 (http://www.biomedical.materialise.com/mimics; Materialise, Leuven, Belgium). The 3D-object was edited (smoothing, colours and lightning) in MeshLab v. 2016 (http://www.meshlab.net; 41) and blender v2.79b (https://www.blender.org; Amsterdam, Netherlands). PLY-files of the main cartilages were produced using Mimics v.17.

本文记述了产自摩洛哥迈德地区晚泥盆世法门阶的小型软骨鱼类（chondrichthyan）Ferromirum oukherbouchi 新属新种（n. gen. et sp.）。该类软骨鱼类保存状态极佳，不仅保留有矿化软组织，还完整保存了头部、鳃部及肩带未发生形变的软骨结构。通过3D打印对头部进行重建后，发现了一种此前未见报道的颌关节类型。本数据集公开了原始裁剪图像堆栈以及单个软骨结构的PLY文件。此外，数据集还包含了用于构建本文支序图的性状矩阵的NEXUS格式文件（nexus-file）。
本数据集多数内容摘录自下述研究：Ferromirum oukherbouchi 新属新种的模式标本由瑞士苏黎世大学使用工业计算机断层扫描仪（industrial computed tomography scanner，型号Nikon XT H 225 ST）完成扫描。数据采集与图像重建参数如下：管电压224 kV，管电流474微安；滤波片为4毫米厚的铜片；各向同性体素尺寸为0.091毫米；采集图像为16位TIFF格式；重建过程使用了XX张8位TIFF图像。图像分析与3D模型重建采用Mimics v.17软件（比利时鲁汶Materialise公司，网址：http://www.biomedical.materialise.com/mimics）完成。3D模型的编辑（包括平滑处理、色彩与光照调整）分别在MeshLab v.2016（网址：http://www.meshlab.net；文献编号41）与Blender v2.79b（荷兰阿姆斯特丹Blender基金会，网址：https://www.blender.org）中进行。主要软骨结构的PLY文件通过Mimics v.17软件生成。
