What is a fossil, and how can scientists determine the age of fossils? What are the most characteristic fossils of the Cretaceous Period? What is rarefaction paleontology? What is Pleistocene stratigraphy? What type of fossil is a dinosaur footprint?
Fossilsgenerally form either as mold fossils or as cast fossils and are either considered a trace fossil or a body fossil. An imprint or the natural cast of a footprint in rock is an example of a mold fossil and a trace fossil, while a mineral deposit in the shape of a shell is an ...
Here is a dinosaur footprint also a type II fossil. Type I fossils can be the actual thing that it once was, like a piece of bone or hair or feather. More often the bone material is replaced by different minerals contained in the liquid of the sediments that buried it. What was once...
3D printed manufacturing significantly reduces energy waste and has a relatively smaller carbon footprint compared to traditional manufacturing processes. Essentially 3D printing is all about producing affordable products in an efficient and effective manner with a target of almost zero waste. Because the ...
Hudson adds that the type of footprint, combined with its age, suggests that it was made by a ferocious Megalosaurus-like dinosaur, with a possible hip height as tall as nearly 10 feet. FOSSILS SHOW PRIMATE-LIKE CREATURES LIVED IN ARCTIC 52 MILLION YEARS AGO ...

reaching up to 8.5 feet long and more than 100 pounds in weight. This enormous size is thought to be down to plentiful atmospheric oxygen on earth during the time Arthropleura existed. Based on the fossils that have been uncovered so far, scientists estimate that the creature lived in North...
These small volcanoes usually have a circular footprint, and their flanks usually slope at an angle of about 30 to 40 degrees. Most cinder cones have a bowl-shaped crater at the top. Cinder cones are found in many parts of the world. Countries that have many cinder cones include: Australi...
Zhang notes a large proportion of a vehicle's carbon footprint is generated at the factory before cars reach the road. The limitations of this study included that the dynamics of electrical vehicle charging were not considered, but it could be an area of future research. ...
(Phys.org) —At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) in Long Island, New York, scientists study high-speed ion collisions that reveal what the universe may have looked like moments after the Big Bang. RHIC is
