Agatized dinosaur bone is a rare form of fossilized dinosaur bone where the original fossilized bone (typically permineralized with calcite) has been re-mineralized (replaced/substituted) with silica-type compounds (agate, jasper, chalcedony, or opal). This bone comes from the Bushy Basin Member of the Morrison Formation, approximately 150 million years old. The large cell structure indicates it came from a theropod (meating-eating dinosaur).
Gibeon is an iron-nickel meteorite that fell in prehistoric times in Namibia. The crystal structure of this meteorite provides a classic example of fine octahedrite and the Widmanstatten pattern is appreciated for its beauty both by collectors and designers of jewelry.
1954: the giant bruise just above the hip of Ann Hodges, pictured, is the result of the only confirmed human meteorite strike.
The impact caused quite the stir in the city of Slyacauga, Alabama when it was made, but despite that rock having hurtled out of space to strike her, Hodges survived after it crashed into her living room that winter’s day.
Willamette Wonder The Willamette meteorite is the largest ever found in North America. A settler named Ellis Hughes found the meteorite in Oregon in 1902 and moved the 15.5-ton iron rock to his own property.
When pallasite meteorites are sliced open and polished, a matrix of stunning yellow crystals are revealed. This specimen was found in 1951 by a farmer in a town called Esquel in the Argentine Patagonia.
Peridotite xenoliths in basalt. Peridote or olivine is a magnesium-iron silicate mineral commonly found in the Earth’s mantle. The photos show “chunks” of green peridote crystals that have broken off from a larger mass and floated into the magma within the Earth’s mantle, before being exposed at the Earth’s surface. Magnesium-iron rich olivine is also commonly found in meteorites. Pallasite meteorites contain olivine crystals mixed with molten iron from the cores of large, diffentiated asteroids.

Weighing 15.5 tons, this iron meteorite is the largest ever found in the United States and the sixth-largest in the world. The smooth surface melted during its blazing entry into the atmosphere, while the pits formed on the Earth’s surface.
The Willamette Meteorite was originally located within the Upper Willamette Valley of Oregon. It was revered as a spiritual being that has healed and empowered the people of the valley by the Clackamas Indians who occupied the region.
As we posted about earlier (http://tinyurl.com/opjg275), tonight is the night when Earth may see an intense meteor shower/meteor storm as it passes through the tail of a comet for the first time.
The Camelopardalids could be the strongest meteor shower of the year, so strong that people have said it could even be a “meteor storm”. They will be best viewed from North America and should peak sometime just after 3:00 a.m. EDT/12:00 a.m. PDT/7:00 a.m. GMT/UTC.
A few viewing tips. First, you’ll have to be awake at that time. Second, get away from cities, city light will make viewing difficult to impossible. Third, your eyes are the best tool for this; telescopes or binoculars will limit how much of the sky you can see and make it difficult to find any. Fourth, if you’re planning on trying to take a photograph, set up for a long exposure. Meteors streak through the atmosphere in seconds and even an intense storm will only generate a few events per minute. Finally, give your eyes some time in just darkness to adjust; look away from cameras, vehicles, street lights, or other light sources.
To find the Camelopardalids, basically look north. The center of this meteor shower, if it happens, should be close to a constellation known as Camelopardalis, the Giraffe, which will start the night just to the west of the North Star (Polaris) and will move downwards during the night.
If you’re in a location where the sky will be blotted out by clouds or by that darned sun, there will be several places streaming views of the sky, including the sky-observing community SLOOH and NASA. Follow the links below for viewing options.
