Revised Age of the Oklahoma Impact
A team from the University of Texas at Austin has reevaluated the timing of the meteor strike near Ames, Oklahoma, concluding it occurred roughly one hundred million years later than previously believed. Earlier assessments had placed the event further back in time.
The crater itself is buried beneath layers of sedimentary rock that have accumulated over eons, leaving no surface trace. Despite being hidden, the structure spans several miles underground and remains a distinct geological feature.
The Ames impact structure also contributes significantly to Oklahoma’s modern economy. Its subsurface characteristics make it a major site for oil and gas extraction, giving it both scientific and industrial relevance.
Adjusting the crater’s age influences interpretations of early Earth environments. A younger impact shifts the timeline for how such events may have affected habitats and potentially steered the course of biological evolution.
