Data from: A permineralized Early Cretaceous lycopsid from China and the evolution of crown clubmosses

Data generated from 3D image of Lycopodicaulis oellgaardii (PB 23753) from the Early Cretaceous of Inner Mongolia (see Herrera et al. 2022).

Lycopod_Reconstructed micro-CT_TIFF Stack.zip: TIFF stack of reconstructed micro-CT scan of PB 23753. Synchrotron imaging performed at beamline 8.3.2 of the Advanced Light Source, Lawrence Berkeley National Laboratory.

Lycopod_scaleinmicrons.hx: Avizo project of micro-CT scan of specimen PB 23753.

Lycopod_3D model.mb: Simplified 3D model of specimen PB 23753. Created by exporting simplified meshes of specimen from Avizo which were then cleaned in Meshlab and rendered using Autodesk Maya.

Lycopod.obj: 3D object files of segmented specimen PB 23753. Mesh created in Avizo and edited in Meshlab.

本数据集的数据源自内蒙古早白垩世奥氏石松茎（Lycopodicaulis oellgaardii）标本PB 23753的三维影像，详见Herrera等2022年的研究。

Lycopod_Reconstructed micro-CT_TIFF Stack.zip：该压缩包内含PB 23753标本的显微CT（micro-CT）重建影像TIFF序列。同步辐射成像实验于美国劳伦斯伯克利国家实验室（Lawrence Berkeley National Laboratory）先进光源（Advanced Light Source）8.3.2光束线完成。

Lycopod_scaleinmicrons.hx：该文件为PB 23753标本显微CT扫描的Avizo项目文件。

Lycopod_3D model.mb：PB 23753标本的简化三维模型文件。其制作流程为：先从Avizo中导出标本的简化网格，随后在MeshLab中完成网格清理，最终使用Autodesk Maya进行渲染。

Lycopod.obj：PB 23753标本的分割后三维物体文件。该网格首先在Avizo中创建，后经MeshLab编辑完善。
