World's first known butt-drag fossil trace was left by a rock hyrax in South Africa 126,000 years ago

Rock hyraxes, known in southern Africa more often as "dassies," are furry, thickset creatures with short legs and no discernible tails. They

Dinosaur footprints from Canada are 1st of their kind in the world | CBC News

Scientists have identified fossil dinosaur footprints from a new species in B.C. and Alberta. They're believed to be the first tracks found

…… He noted that trackways often show multiple species that lived together at the same time, and can reveal other information. This new trackway also shows that wide, squat ankylosaurs — sometimes described as being coffee-table-like — had a surprisingly bird-like gait, lining up left and right feet like "supermodels on a runway." He added, "This track record shows us the coffee table analogy is a little bit flawed." On the other hand, he acknowledged, there is one drawback of footprints compared to bones. "The obvious question is: What do these animals look like? All we have are the feet."

Tiny mussel imprints

Sometimes I wonder how many tiny fossils, imprints of mussel or brachiopode we missing around in all the pieces of rocks, or rock matrix.

Meistens hier typisch Feuerstein Flint, brüchige gespaltene Scherben mit kleinen Muschelabrücke, teils mit Schalenmuster, aber keine art Bruch muschelig. Teils kristallisierte.

"Drought has dried up part of a river in central Texas, revealing 113-million-year-old dinosaur tracks. The prehistoric footprints emerged at Dinosaur Valley State Park, which is located in the town of Glen Rose, southwest of the Dallas-Fort Worth area. As the name suggests, the park already protects other dinosaur footprints. But the tracks that recently emerged are usually hidden under the mud, silt and waters of the Paluxy River. This summer, however, water levels have dipped so low that the prehistoric indentations are now visible. So far, volunteers have counted 75 newly exposed footprints in the parched riverbed. “It has been another very hot, very dry year, so our researchers are trying to take advantage of the drought,” says park superintendent Jeff Davis to the Dallas Morning News’ Sarah Bahari. Two different types of dinosaurs likely made the footprints, according to park officials. One was Acrocanthosaurus, a 15-foot-tall carnivore that weighed approximately 14,000 pounds. As the gargantuan reptile walked around the area on two legs, it left behind the outline of its three-toed feet. The other was Sauroposeidon proteles, which has been the official state dinosaur of Texas since 2009. This long-necked behemoth may have measured up to 100 feet long and weighed closer to 88,000 pounds. It left behind larger, bulbous-shaped tracks that are similar to elephant footprints."

Feeding patterns

These swirly patterns were made by living organisms at the bottom of the sea approximately 250 million years ago while they were feeding on an organic matter mixed within the sediment. The pictured sediments were buried by more sediments, hardened and eventually brought to the surface by tectonic processes without messing up such signs of ancient life.

So many fossils from Guadalupe Mountains National Park. Check out the Permian Reef Geology Trail. If you have several days you can hike it all the way to Carlsbad.
