"Unearthing a Vintage Insect Sphere"
Researchers have discovered a 50-million-year-old fossil katydid with remarkably preserved soft tissues, including a testicle. The fossil, named Arethaea solterae, was found in northwestern Colorado and is the first known preserved testicle in a fossil insect. The discovery sheds light on the internal anatomy of ancient insects and suggests that there may be more well-preserved soft tissues waiting to be found in other fossils.
