Yes, there are other contributing factors such as global warming, pollution, predation and angling, but the single largest impactor is the drift net. |
This sample was crushed to 600 microns using the Vertical Shaft Impactor and then concentrated using a wave-table into five individual concentrates. |
They found that impacts were hot enough to release a mix of gas and liquid from the destroyed impactor. |
The impact of the impactor would have turned the sky red hot, the atmosphere would have been filled with dust and the tops of oceans would have boiled, the researchers said. |
Sediments from the crater indicate that the impactor must have been a carbonaceous chondrite, an especially primitive meteorite. |
The implant is first hammered into place attached to an inserter, which is removed, and the surgeon uses a final impactor to fully engage the implant lugs. |
