What else can I help you with?
Which came first trilobites or ammonites how did you know?
Trilobites are older than ammonites, with trilobites appearing first in the fossil record about 521 million years ago during the Cambrian period, while ammonites appeared later, around 400 million years ago during the Devonian period. Scientists determine the age of fossils based on their position in rock layers and radiometric dating techniques.
When was The Trilobites created?
The Trilobites was created in 1984.
What is an ancient fossil that are found in dome-shaped rocks composed of thin layers of sediment pressed tightly together called?
Trilobites are ancient fossils commonly found in dome-shaped rocks composed of thin layers of sediment. These creatures have a hard exoskeleton that can be well-preserved in sedimentary rocks.
Time when trilobites and fish arrived?
Trilobites first appeared in the Cambrian Period around 521 million years ago, while fish began to emerge around 480 million years ago. This evolutionary timeline suggests that trilobites appeared earlier than fish in Earth's geological history.
The prokaryotic cells that built stromatolites are classified as?
The prokaryotic cells that built stromatolites are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the formation of stromatolites, which are layered structures formed by the trapping and binding of sediment by microbial communities.
Did trilobites come before stromatolite?
No, stromatolites are bacterial mats and have been around for at least 2,700,000,000 years. Trilobites only appear in the fossil record about 526,000,000 years ago.

When did Stromatolites become extinct?
The are examples of stromatolites still living. They are not extinct.
When was The Trilobites created?
The Trilobites was created in 1984.
What (who)are stromatolites?
The stromatolites are the layered mounds, columns, and the sheet-like sedimentary rocks.
Did trilobites bite?
Trilobites did not have jaws, therefore they could not bite.
Are Trilobites land animals or water animals?
Trilobites are extinct but they were marine animals.
What are the oldest fossils?
Stromatolites.
How is a structure built?
Stromatolites
