Best part (besides the fossils)? Horses and ranch hands pitching in to move the fossil-rich rock matrix!

Those shifts stacked up distinct layers: tough sandstone from the swift flows, and softer mudstone from calm water. Think of it like pages in a rock history book. Here’s the cool part: the best, fully connected fish fossils often appear exactly where a sandy layer meets a muddy one.

Excavated from the Pisces Point locality of Scollard Formation in Alberta, Canada, ~67 million years old, Acronichthys maccognoi, newly reported in @science.org, was recovered from ancient water body that flipped seasonally between fast-flowing channels and quiet, still pools.

New in @science.org, meet Acronichthys maccagnoi, a new species from Late Creatacous Canada that changes what we know about the origins and evolution of one of the most successful fish groups on Earth.
