STL Files of Lystrosaurus Perinate Specimens from the Early Triassic

Three perinate specimens of the dicynodont genus Lystrosaurus from the Early Triassic of the South African Karoo Basin. The data comprises high-resolution CT and synchrotron scan files, shared by author Julien Benoit and last updated in April 2026.

Use Cases

• 3D modeling of fossil specimens based on high-resolution CT and synchrotron scan data
• Analyzing embryonic posture and developmental traits in non-mammalian synapsids
• Comparative studies of egg size and reproductive strategies across synapsid lineages
• Investigating the link between reproductive biology and resilience after mass extinction events

Strengths

• Data includes high-resolution CT and synchrotron scans of rare perinate specimens
• Focuses on Lystrosaurus, a non-cynodont synapsid offering a glimpse into plesiomorphic reproductive biology
• Released 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
• No calcified eggshell is preserved, as noted in the description
