One of the now rare species of oysters in the Pacific Northwest is the Olympia oyster, Ostrea lurida, (Carpenter, 1864). While rare today, these are British Columbia’s only native oyster. Had you been dining on their brethren in the 1800s or earlier, it would have been this species you were consuming. Middens from Vancouver Island's norther tip to California are built from Ostrea lurida.
An exquisite fossil specimen of an Eusthenopteron Fordi from the upper Devonian (Frasnian), Eescuminac Formation, Miguasha Park, Bay of Heat, Gaspé, Quebec, Canadian Museum of Natural History, Miguasha Collection.If you look closely at this specimen, you can see the remarkable 3-D and soft-bodied preservation. This fish specimen reminds me of the ray-finned fossil fish you see in carbonate concretion from Lower Cretaceous deposits in the Santana Formation, Brazil.
This fossil specimen of the fruit of the lotus, Nelumbo, was found by Green River Stone (GRS) in early Eocene outcrops of the Fossil Lake Member of the Green River Formation. The awesome possums from GRS are based out of North Logan, Utah, USA and have unearthed some world-class specimens. They've found Nelumbo leaves over the years but this is their first fossil specimen of the fruit.
Researchers have published the results of the largest prospective multicenter trial conducted of FDG-PET/CT in head and neck cancer, providing data on clinical decision-making.
When there are more free radicals present than can be kept in balance by antioxidants, the free radicals can start doing damage to fatty tissue, DNA, and proteins in your body.
Ever wonder why the slow moving sloth has a slightly greenish hue? Ever consider the sloth at all? Well, perhaps not. Location, location, location, is the mantra for many of us in our macro world, but it is also true for the small world of algae.
The Miocene pillow basalts from the Lake Roosevelt National Recreation Area of central Washington hold an unlikely fossil mold of a small rhinoceros, preserved by sheer chance as it's bloated carcass sunk to the bottom of a shallow pool or lake just prior to a volcanic explosion. We've known about this gem for a long while now. The fossil was discovered by hikers back in 1935 and later cast by University of California paleontologists in 1948.
Quintus Sertorius, a Roman statesman come general, grew up in Umbria, the green heart of what is now central Italy.Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from the hills, mountains, and valleys of his birthplace. In 81 BC, he traveled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.
The Earth has a magnetic field with north and south poles. The magnetic field of the Earth is surrounded by the magnetosphere that keeps most of the particles from the Sun from hitting the Earth.
Have you ever wondered about the colors you see in these moments? What sunlight actually is? Yes, it's light from the Sun but so much more than that. Sunlight is both light and energy. Once it reaches Earth, we call this energy, "insolation," a fancy term for solar radiation. The amount of energy the Sun gives off changes over time in a never ending cycle. Solar flares (hotter) and sunspots (cooler) on the Sun's surface impact the amount of radiation headed to Earth.
During the early Triassic period, ichthyosaurs evolved from a group of unidentified land reptiles that returned to the sea. They were particularly abundant in the later Triassic and early Jurassic periods before being replaced as premier aquatic predator by another marine reptilian group, the Plesiosauria, in the later Jurassic and Cretaceous periods.
