Are trilobite fossils older than fish fossils?

No. Trilobytes are the oldest fossils ever found. They are the reason the theory of evolution is still only a theory. They were complex organisms with all the basic organs, complex eyes and a respitory sytem. If evolution is true, why for over two centuries have no fossils been found leading up to their evolutionary "place."


The oldest vertebrate fossils are those of ------- with no jaws?

Agnatha, also known as jawless fish, are the oldest vertebrate fossils with no jaws. This group includes ancient species like the ostracoderms and the agnathan fish.


How are fish fossils formed?

Fish fossils are formed when a dead fish is buried in sediment that eventually hardens into rock. Over time, the organic material in the fish decays, leaving behind a cavity that gets filled in with minerals. These minerals create a cast of the fish's body, which becomes a fossil.


If you found ocean fish fossils below land animals fossils what would that tell you?

It would tell you that an ocean once existed there and then withdrew.


What were the earliest vertebrae water dwelling fossils?

The earliest vertebrate fossils found in aquatic environments date back to the Cambrian period, approximately 500 million years ago. Notable examples include the jawless fish known as Agnatha, with one of the oldest genera being Myllokunmingia. These early vertebrates exhibited primitive features and laid the groundwork for the evolution of more complex fish and terrestrial vertebrates. Fossils from this era provide crucial insights into the transition from invertebrates to early vertebrates in the evolutionary timeline.

Why were Tiktaalik fossils found in the arctic even though the fish was thought to be from tropical locals?

Tiktaalik fossils were found in the Arctic because the region was warm and had a more temperate climate during the time when the fish lived. The movement of tectonic plates over millions of years shifted the location of the Arctic from a tropical area to a colder climate. This is why fossils of Tiktaalik, which originated in a warm marine environment, are now discovered in the Arctic region.
