Prepping over one specimen to reach another can feel daunting, but sometimes it’s a necessary sacrifice to reveal the science hidden below. This freshwater stingray lies just beneath a mass-mortality layer within the Fossil Butte Member of the Green River Formation—specifically within the Sandwich Beds. Careful preparation through these stacked laminations helps us document the paleoecology of this ancient lake system and preserve the fine details that make specimens like this so significant. #P
