Microscopic photo of a thin section of calcareous tufa of Holocene age.
Ammomite (Ammomoideae) fossil imprint on a limestone. The image was captured in the canton of schaffhausen during springtime.
An eroding rock with fossil inclusions surrounded by beach rock swash deposits.  These types of rocks are fairly common to find on NW USA beaches for those with a keen eye.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Explore fossil limestone slabs from Ruegen featuring petrified brachiopods, providing insights into ancient marine environments.
