Where do devonian live?
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.
What evidence implies that overturning may have occurred during the late Devonian?
Fossil evidence from late Devonian rocks show that some groups of marine organisms experienced significant extinction events, which may suggest a period of environmental upheaval. Sedimentary records also indicate abrupt changes in sea levels and climate during this time. The presence of specific isotopic markers in the rock record can further support the theory of overturning during the late Devonian.
What did the earths surface look like in the devonian time period?
During the devonian time period most of land was under water.
When did the first insect appear?
Insects are one of the oldest groups of organisms, with fossil evidence suggesting they appeared around 400 million years ago during the Devonian period.
What is a common Devonian fossil?
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.
What organisms first appeared in the Devonian period?
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.
Which type of fish evolved during the Devonian?
Fish and molluscs were the dominant creatures during the Devonian.

How was the carboniferous period different from the devonian period?
The Carboniferous period followed the Devonian period and was characterized by extensive coal forests and the emergence of early reptiles. The Devonian period is known for the diversification of fish and the development of forests on land.
What Devonian organisms are still alive today?
Scorpions, sharks... I don't know!

Were there flowers during the Devonian Period?
during the devonian period early amphibians developed also ferns, seed plants, and bearing plants appear on land
Is the Devonian time before or after the mass extinction?
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.
