The first plants with spores, which indicates that they were land plants, appeared in the Middle Ordovician period, about 470 million years ago. First records of tetrapods, or land animals, show up in the fossil record around 370 million years ago.

When did abundant fossil evidence first appear in the geologic record?
The first abundant fossil evidence first appeared during the Paleozoic Era. It was the first era of the Phanerozoic Eon, which occurred 540 million years ago.
When did fish first appear in the fossil record?
The first known vertebrate fossils, found at the Chengjiang locality in China, date back to the early Cambrian. These early vertebrates, such as Haikouichthys, are small, tapered, streamlined animals showing eyes, a brain, pharyngeal arches, a notochord, and rudimentary vertebrae. Vertebrates appear to have radiated in the late Ordovician, about 450 million years ago. However, most Ordovician fossil fossil vertebrates are rare and fragmentary, although available material suggests that ancestors of the sharks and jawed fish were present along with various lineages of armored jawless fish. By the middle Silurian, about 400 million years ago, the picture is clearer: the armored jawless fish were quite diverse, and the first definite jawed fish had appeared -- the Silurian is sometimes called the "Age of Fishes." By the late Devonian, 360 million years ago, early cartilaginous fish and bony fish were diversifying.
What are two things that scientists learn from the fossils record?
The fossil record provides evidence about the history of life and past environment on earth. The fossil record also shows that different groups of organism have changed over time.
What is the definition of range of a fossil species?
The range would be the span of time between the point in the geologic record the fossil organism first appeared to the point in the geologic record that the organism last appeared.
In what type of rock do most fossils appear?
Rarely a fossil may appear in metamorphic or igneous rock, but the vast majority of fossil evidence presents itself in sedimentary rock. Remains or evidences of life are often preserved by being covered in sediments before decaying or being consumed by predators. The sediments may turn to rock through the process of lithification over time, leaving a record of their presence.Limestone - by far
Why is the fossil record unable to provide a full portrait of the times in which the fossilized animals and plants lived?
The fossil record is incomplete.

Which evidence for evolution uses impressions of plants and animals pressed into sedimentary rock?
The evidence for evolution that uses impressions of plants and animals into sedimentary rock is the study of fossils. The study of fossils and where they are found is a determining factor about what was going on in a period of history.
Any precambrian tine animals and plants that have turned into fossils?
Yes, although the fossil record for the precambrian period is scarce. See related link.

Dinosaurs and fish
