Vertebrates developed about 550 million years ago. The oldest vertebrate fossils are those of with no jaws.?
The oldest vertebrate fossils, dating back about 550 million years, belong to jawless fish, specifically groups such as agnathans. These early vertebrates lacked jaws and were characterized by their simple structures, relying on filter-feeding or scavenging for sustenance. Over time, vertebrates evolved more complex features, including jaws, which allowed for a greater variety of feeding strategies and contributed to their diversification.
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.

Do the oldest rocks on earth contain fossils?
Maybe. It depends on what kind of rock it is. If its a sedimentary rock and it's pretty old, then it will probably have some fossils in it. If its igneous the chances are not very likely i'd say.
List of vertebrates non vertebrates animals?
vertebrates are fish, and invertebrates are slugs
What is the significance of the oldest animal fossils on Earth in understanding the history of life on our planet?
The oldest animal fossils on Earth are significant because they provide important clues about the early evolution and diversity of life on our planet. By studying these fossils, scientists can better understand how animals first appeared and evolved over time, shedding light on the history of life on Earth.
