STL Files of Lystrosaurus Perinate Specimens from the Early Triassic Karoo Basin

Three perinate specimens of the dicynodont Lystrosaurus from the Early Triassic of the South African Karoo Basin are provided as STL files. The data was generated by author Julien Benoit using high-resolution CT and synchrotron scanning. The dataset was last updated on 2026-04 09.

Use Cases

• Analyze embryonic posture and development based on the tightly curled, in ovo position described.
• Study tusk development and jaw fusion patterns in pre-hatching synapsids.
• Model soft-shelled egg morphology and size for non-cynodont synapsids.
• Compare reproductive strategies between Lystrosaurus and more derived cynodonts like Kayentatherium.

Strengths

• Data derived from high-resolution CT and synchrotron scanning.
• Focuses on a rare non-cynodont synapsid, offering a glimpse into plesiomorphic reproductive biology.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is 62.1 MB, which is a small scale for 3D scan data.
