This dataset provides a 3D reconstruction of a fossil specimen from the palaeontological collection of the Musée national d'histoire naturelle Luxembourg (MNHNL). The reconstruction was created using photogrammetry, a technique that generates 3D models from overlapping 2D photographs.

Taxon: Proacirsa angulata

Time period: zone à Sonninia sowerbyi, Lower Toarcian (183.7 to 181.6 million years ago)

Collection location: Bettembourg, Luxembourg

The original specimen of this fossil is kept at the palaeontological collection of the Luxembourg National Museum of Natural History (MnhnL) in Luxembourg.

This dataset contains:

1. Online 3D Model: A link to an interactive, viewable version of the 3D model hosted on Sketchfab.
2. Original Photogrammetry Images: The complete set of high-resolution photographs used to create the 3D reconstruction.
3. 3D Model Files: Multiple resolutions of the 3D model in .obj format, including corresponding texture files as raster images. These files can be viewed and processed offline using MeshLab.
