What animals went extinct in the late Devonian?
The corals that built the Devonian reefs, the famous bottom-feeding creatures known as trilobites and ammonites, and the armoured placoderm fish such as Dunkleosteus: all of them took a clobbering. But it's not clear why. When the dinosaurs went extinct 65 million years ago, there was an obvious culprit.
Explanation:
What happened during the Devonian period?
The Devonian seas were dominated by brachiopods, such as the spiriferids, and by tabulate and rugose corals, which built large reefs in shallow waters. Encrusting red algae also contributed to reef building. In the Lower Devonian, ammonoids appeared, leaving us large limestone deposits from their shells.Why is the Devonian called the Age of Fishes?
The Devonian, part of the Paleozoic era, is otherwise known as the Age of Fishes, as it spawned a remarkable variety of fish. The most formidable of them were the armored placoderms, a group that first appeared during the Silurian with powerful jaws lined with bladelike plates that acted as teeth
Determine the general wave and longshore sediment transport directions by determiing where the sand is against where it is eroding, is heaping up.
from the top to the bottom
- The direction of beach drift
- Groyne
- The incoming wave direction
-The direction of the longshore current
<h3>What is longshore sediment transport?</h3>
- The collective movement of beach and nearshore sand parallel to the shore caused by the combined action of tides, wind, and waves, as well as the shore-parallel currents produced by them, is referred to as longshore transport.
- Usually, these forces cause sand to move practically continuously, either in bedload flows or suspension.
- This happens in an intricate, three-dimensional pattern that changes quickly over time.
- Sand in the area of interest may occasionally have an upcoast component whereas other sand is often migrating downcoast.
