Paleontologists Uncover Ancient Egg from Mammal Ancestor

First therapsid egg from Lystrosaurus found in South Africa's Karoo Basin.
Confirmed via synchrotron scans after 17 years of study.
Julien Benoit identified incomplete jaw fusion, indicating embryo death before hatching.
Egg had soft shell with yolk, supporting development without parental care.
Discovery supports Lystrosaurus' survival after End-Permian Mass Extinction.
Study shows resilience in species during extreme environmental changes.
