The oddly shaped skull of Leptarctus primus, an extinct weasel relative that lived in North America and Asia about 20 million years ago, has long led to conflicting theories about its diet. But new biomechanical models show that Leptarctus was likely a carnivorous predator, with capability for omnivory and a broader diet when prey was […]
Scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact […]
A major volcanic event could have triggered one of the largest glaciations in Earth's history -- the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers have discovered remnants of such a large igneous province that resulted from vast lava flows.
Geophysicists used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. Their statistical model didn't allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top […]
@TetZoo it's known as the proroca phenomenon that is when the ocean runs into the river during high tides... they are specially high when the rainy season is ending and thus the volume of water out of the amazon river is decreasing a bit https://t.co/aokARFa1VA
@TetZoo this was flood area at the mouth of the amazon river.. seems this time of the year the tides are wilder because the rain regimes are changing between river and sea. they also think the whale was already dead when was dragged there
