324-Million-Year-Old Fossil from Texas Reveals Insect Land Colonization

A newly described fossil, Chosha praecursor, from Texas, dated to 324 million years ago, fills a key gap in insect evolution, showing how insects transitioned to land. The discovery resolves an 80-million-year-old mystery in the fossil record, providing direct evidence of early insect terrestrial adaptation. This is a fundamental paleontological finding that reshapes understanding of insect phylogeny and terrestrialization.
