Why Geologists Love Pond Scum

If you’ve ever wondered how geologists know so much about ancient beaches and shallow oceans — from the paleoenvironment to the animals roaming around, the seasonality of the weather, and even the time of day when the ancient scene was preserved — they owe it all to the sand particles bound together by microbes, forming…

Ancient Tidal Flats Were Busier Than We Thought

New trace fossil discoveries from the half-billion-year-old Cambrian tidal flats of Wisconsin at a site called Blackberry Hill continue to paint the picture of some of the earliest animals to set foot on land and what they might have been eating. The mollusk trail Climactichnites blackberriensis (Cb) presumably stopping to eat a scyphozoan (jellyfish) that…

Californian Hybrid Honeybee Population Has Evolved Natural Defense against Varroa Mites: Study

Honeybees (Apis mellifera) are important ecological and agricultural pollinators. In the United States, beekeepers experience substantial annual colony losses, largely driven by parasites such as the mite Varroa destructor. In new research, scientists studied a hybrid honeybee population in Southern California, a genetic mix of Western European, Eastern European, Middle Eastern, and African lineages. They…

Permian Fossil is Earliest Evidence of Rib-Powered Breathing

Paleontologists have examined 289-million-year-old specimens of the early reptile Captorhinus aguti that preserve a covering of three-dimensional skin, a complete shoulder girdle and ribcage with cartilages, and — most astonishingly — protein remnants that predate the previous oldest-known example by nearly 100 million years.

500-Million-Year-Old Fossil Identified as Oldest Known Chelicerate

Paleontologists at Harvard University have described a large predatory arthropod from the Middle Cambrian of Utah featuring massive three-segmented chelicerae. Named Megachelicerax cousteaui, this soft-bodied animal represents the earliest known member of the chelicerates, pushing back the origins of spiders, scorpions, horseshoe crabs, and sea spiders by 20 million years. The surprisingly complex anatomy of…
