Irving power plant on Fossil Creek. The plant and was decommissioned in 2005. The dam, flume, buildings, and other structures were removed. The creek was designated a "Wild and Scenic River" in 2009.
Fossil Creek is one of only two National Wild & Scenic rivers in Arizona and is fed by springs coming from the cliffs of the Mogollon Rim. Over 30 million gallons of water are discharged each day at a constant 70°F. The high mineral content leaves travertine dams and deposits, giving rise to fossil-like features.
In 2005, Arizona Public Service (APS) decommissioned the Fossil Creek Dam and Flume, restoring full flows to Fossil Creek. The diversion dam at Fossil Springs was partially removed, allowing the creek to flow freely. The flume that once carried water to the power plant was disassembled. The Irving power plant and other buildings around the site were removed. Traces of history remain visible at the Irving site and along the Flume Trail in the form of old building foundations, rock work along the flume's maintenance road, and concrete pilings that once supported the flume.

I have another Zlichovaspis that also has this red coloring. I wonder if there is a bit of iron in the soil that oxidized after excavation. It really doesn’t appear to be applied. The rest of this trilobite is more of a flat, olive color, completely natural, with absolutely no signs of a coating. And check out the great oval trace fossil on the right side. Probably a XS through another trilobite. This Devonian specimen is also from Morocco, Atlas Mountains and measures 77mm.
I seem to have discovered a mystery. I have contacted local museum, local and county geological societies, and Sedgewick Geology Museum at Cambridge. They confirm it is a fossil tree, but have no knowledge of it. How old is it? How did it get here - erratic or human agency? What species of tree is it?
Anyone got any thoughts on this?
Fossilized brachiopods , Malmøya, Norway. These fossils are quite common at certain places in the Oslo region. They are from the silurian period (445-415 million years ago), a short but important time period, when life truly startet to colonize land (with primitive plants). These brachiopods were not terrestrial though.
Neat way of arranging the hands on this Fossil watch, designed by Philippe Starck. It's amazing what you'll buy on a long haul flight!
This was taken at Fossil Creek. We just took a recent trip to Cottonwood, AZ for our July 4th. We enjoyed swimming here one afternoon! We had to drive 10 miles on rough terrain up a mountain to get this beautiful spot!
My Fossil watch.
Sadly during this shoot, I dropped it and scratched the bezel and shortly after the kinetic technology that supplies power to the second hand stopped working
Fossil Creek is in the Coconino National Forest in Arizona. The water from this creek was used in the early 1900's to supply water to a hydroelectric power plant that was used to produce electricity for nearby mining operations. The green/blue color of the creek is due to calcium carbonate deposits.
Ancient fossils, seen here in rocks of the Jurassic Coast in Dorset, England.
The Jurassic Coast is a UNESCO World Heritage site, stretching nearly 100 miles from Devon to Dorset, and covering nearly 200 million years of Earth's geological history.

These specimens appear to be in limestone.
Ammonoids are common & conspicuous fossils in Mesozoic and some Paleozoic marine sedimentary rocks. Ammonoids are an extinct group of cephalopods - they’re basically squids in coiled shells. The living chambered nautilus also has a squid-in-a-coiled-shell body plan, but ammonoids are a different group.
Ammonoids get their name from the coiled shell shape being reminiscent of a ram’s horn. The ancient Egyptian god Amun (“Ammon” in Greek) was often depicted with a ram’s head & horns. Pliny’s Natural History, book 37, written in the 70s A.D., refers to these fossils as “Hammonis cornu” (the horn of Ammon), and mentions that people living in northeastern Africa perceived them as sacred. Pliny also indicates that ammonoids were often pyritized.

Ammonites
Ammonites are extinct molluscs of the Class Cephalopoda, a group represented today by the octopus, squid, and shell-bearing Nautilus. Ammonites appeared midway through the Paleozoic Era (400 million years ago). They diversified many times over their 300 million year history, and persisted through three mass-extinction events. During the Mesozoic Era (from 250 to 65 million years ago), ammonites reached their greatest diversity, achieving many different shell forms and ways of life. At the end of the Mesozoic Era, ammonites became extinct, together with the dinosaurs, pterosaurs, and marine reptiles.
Ammonite Anatomy
Ammonites, like the modern Nautilus, possessed an external shell divided into a series of chambers by thin walls called septa. These chambers were connected by a flesh-bearing tube known as the siphuncle. By analogy with the living Nautilus, it served to regulate fluid and gas levels in each chamber, enabling ammonites to control their buoyancy. Although ammonites are common fossils, little is known about their soft parts. However, it is thought that their soft anatomy was similar to that of modern squid and octopi. They probably possessed eight to ten arms surrounding a beak-like mouth. Locomotion probably involved bringing water into a cavity, formed by the fleshy mantle, then expelling it by muscular contraction through a funnel-like opening called the hyponome, therby implementing a form of jet-propulsion.
Ammonite Ecology
Ammonites were common constituents of Cretaceous marine ecosystems and were represented in many habitats in the shallow seas that covered North America during the Mesozoic Era. Ammonites lived in both nearhsore and offshore settings in both benthic (seafloor) and pelagic (open ocean) habitats. Some species could probably even migrate between both types of habitats.
Feeding Habits
Most ammonites, like their modern cephalopod relatives, were probably carnivores, although some may have been passive planktivores. The carnivorous ammonites possesssed powerful jaws adapted for crushing prey, which included crustaceans, fish, clams, snails, and even other ammonites.
Reproduction and Growth
Ammonites, like their modern relatives the octopi and squids, hatched as tiny larvae in huge numbers and probably grew to maturity within a short span of time. Most adults were small, while those of some species were huge, reaching sizes greater than 6 feet (2 meters) in diameter. Aberrant ammonites that changed their shape during growth are thought to have changed their habitat as well.
Ammonite Sexes
Like modern cephalopods, ammonites showed distinct differences between sexes. Shells of female ammonites, known as macroconchs, are larger and possess little or no ornamentation. Males, known as microconchs, are smaller than females and commonly possess distinct ornamentation.

Fossil Crinoids (Jimbacrinus bostocki). Found in the Grascoyne Formation of Permian age. These crinoids are about 280 million years old. Gascoigigne Junction, West Australia, Australia. (Collection of the Colorado School of Mines Geology Museum. Golden, Colo.)
Closeup of what looks like a fossil in the rock face with the Barrier Canyon Style pictographs. This part of the panel is faded from runoff, but from looking at it in DStretch this looks like it was on the side of a painted figure, maybe about where its arm would be. But I can't really make out enough to see if the artist was trying to incorporate it or ignore it.
Fossil Free Oxfordshire celebrates that Oxford City Council has become the first local authority in the UK to pass a motion on fossil fuel divestment. The Council pledged to make no direct investments in fossil fuel companies for ethical reasons.

Fossil Butte, a mesa composed of the Green River Formation. This fossiliferous limestone was precipitated from calcium-rich waters during the Eocene about 50 million years ago. The limestone is interbedded with many thin layers of volcanic ash and mudstone. Quarries on the butte were the source of many of the fossils displayed at the Monument visitors center. Fossil Butte National Monument. Near Kemmerer, Lincoln Co., Wyoming.
