ysabetwordsmithScientists just solved a 160-million-year fossil mystery “I’ve never seen anything like it”
A rare fossil reveals that Earth’s earliest sponges were hiding in plain sight—too soft to leave a trace.
A rare fossil discovery is shedding light on the “missing years” of early sponge evolution. Scientists found a 550-million-year-old sponge that likely lacked hard skeletal parts, explaining why earlier fossils are so scarce. This supports the idea that the earliest sponges were soft-bodied and rarely preserved. The finding changes how researchers hunt for the origins of animal life.
Well, that was obvious. Soft organisms typically predate those with rigid parts that preserve better. It's still really cool to find evidence.
