AI에 의해 보고됨
An international team of researchers has discovered a 151-million-year-old fossil of a non-biting midge in Australia, the oldest known from the Southern Hemisphere. This find, named Telmatomyia talbragarica, reveals freshwater adaptations previously linked only to marine species, suggesting the Chironomidae family originated in Gondwana. The discovery reshapes understanding of ancient insect biogeography.

A tiny fossil fish discovered in southwestern Alberta is the oldest North American otophysan, offering new insights into the evolution of freshwater fish species. Named Acronichthys maccognoi, the 4 cm specimen from the Late Cretaceous period suggests otophysans transitioned from marine to freshwater environments at least twice. The find, detailed in a study published on October 2 in Science, challenges previous understandings of their global spread.
