A new study by a Canadian Museum of Nature scientist helps answer a long - standing question in palaeontology — how numerous species of large, plant - eating dinosaurs could co-exist successfully over geological time.
In Charles Lyell's 1830 Principles of Geology, he identified the burrows of marine fossils at the top of the Macellum of Pozzuoli (an ancient Roman market building), concluding that the ground around Naples rises and falls over geological time.
In this process, also known as the biological pump, atmospheric CO2 is stored in sedimentary deposits over geological time periods.
S: Comets are very important in terms of the hazard they pose to Earth's ecosystems over geological time, and they're the best samples we have of the primordial material that formed the solar system.
Paleontologists are already using the new results to reexamine the spread of plants and animals across the continents over geological time.
Comparing those sequences from many different species could reveal evolution's handiwork over geological time, much as studies of ancient DNA do today.
Better yet, more of it was in the crystalline calcite form, which is more stable — and likely to sequester CO2 over geological time — than amorphous CaCO3.
