The Devonian period is a geologic time period that occurred approximately 419 to 359 million years ago. During this time, life existed in various forms, including fish, plants, and invertebrates. The organisms living during the Devonian period inhabited environments such as oceans, rivers, and landmasses that are now part of present-day continents.
Because in areas where the rocks are layered, the Devonian is found lower.
A common Devonian fossil is the trilobite, which was an ancient marine arthropod with a hard exoskeleton. Trilobites were diverse and abundant during the Devonian period, with many different species found in rocks from this time period. Their distinctive appearance and widespread distribution make them one of the most well-known fossils from the Devonian period.
During the devonian time period most of land was under water.
The Devonian period lasted for approximately 60 million years, from about 419 million years ago to 359 million years ago.
there was plate tectonic movement
Which mass extinction? There have been five such events. The first one, the Ordovician-Silurian extinction event occurred before the Devonian. The Late Devonian event occurred during the Devonian. All other mass extinctions occurred after the Devonian.
The Devonian Period
If I'm correct, they appeared after the Devonian era. You might want to google that s**t though.
The area of Devonian Gardens - Calgary - is 10,117.141056 square meters.
Fish and molluscs were the dominant creatures during the Devonian.
Because in areas where the rocks are layered, the Devonian is found lower.
Fish first appeared in the Cambrian period, long before the Devonian.
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
The Devonian Period is sometimes referred to as the age of the fish. Forests and the coiled shell-bearing marine organisms known as ammonites first appeared early in the Devonian.
During the devonian time period most of land was under water.
