A key link in turtle evolution has been discovered, with a fossil found that sheds light on the development of turtles. The fossil, which is reportedly 228-million-year-old, shows a turtle without a shell but with a toothless beak. However, reports on the discovery's implications vary, with some outlets discussing its relevance to turtle evolution, while others mention unrelated topics such as human ancestors, bird genetics, and the evolution of human and reptile hearts.
