Later fossils show that horses changed as well. They became taller, which would help them see predators while they fed in tall grasses. They evolved a single large toe that eventually became a hoof. This would help them run swiftly and escape predators.
What does the fossil record show about the history of the horse?
A dog-like organism gave rise to the first horse ancestors 55-42 million years ago. The fossil record shows modern horses moved from tropical forests to prairie habitats, developed teeth, and grew in size. The first equid fossil was a tooth from the extinct species Equus curvidens found in Paris in the 1820s.

What are 3 important limitations of the fossil record?
The fossil records suffer from 3 types of bias: temporal bias, geographic bias and taxonomic bias. Fossil of certain geologic time may be easier to find as compared to those or other era, such as newer fossils are easier to find than older ones.
What can we learn from fossil records quizlet?
What can be learned from the fossil record? The fossil record provides evidence about the history of life on Earth. It also shows how different groups of organisms, including species, have changed over time. Which type of dating provides an absolute age for a given fossil?
How do paleontologists learn about evolution?
Paleontologists look at fossils, which are the ancient remains of plants, animals, and other living things. Fossils are mainly formed in two ways. … Paleontologists use fossil remains to understand how species evolve. The theory of evolution says that living species change over a long period of time.

What does the fossil record show about how life has changed on earth?
Fossil records show evidence of how living organisms have evolved or changed over time. Paleontologists were able to detect the particular order in which these organisms have lived. For instance, simpler organisms inhabited older rocks and complex organisms were found in younger rocks.
What do patterns in the fossil record teach us about changes on Earth?
One pattern in the fossil record is the presence of forms with transitional characteristics, arranged in sequential stratigraphic order. This means that the fossil record provides evidence for evolution and it shows tiny changes in the structures of organisms as time moved forward.
