444-Million-Year-Old Fossil Preserves Muscles but Lacks Head and Legs
Scientists discovered a 444-million-year-old marine fossil of a new species named Keurbos susanae. The fossil remarkably preserves internal structures such as muscles, tendons, connective tissues, and digestive remains in great detail, despite missing its head, legs, and most of its hard outer shell. This finding provides unique insights into ancient marine life anatomy.
