Question

The La Brea Tar Pits in Los Angeles are the site of millions of fossils from the ice age. Woolly mammoths, giant sloths, dragonflies, and other plants and animals from this era have been found in these pits.

Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles’ climate history by studying the specimens found in these tar pits?

Answer 1

Answer:

231 species

Explanation:

More than one million bones were recovered in 1906. These bones represented 231 species of vertebrates and there were 234 species of invertebrates.

Los Angeles climate is relatively stable for over 50,000 years. The fossils of more than 180 insects were preserved in La Brea Tar Pits. The climate warming probes a link for evolution of Ice Age predators.

Answer 2

Explanation:

Mammals like sabertooths and mammoths both are extinct because Its reliance on large animals has been proposed as the cause of its extinction, along with climate change and competition with other species, but the exact cause is unknown.

The second question you can do independently, but anyways hope this helped you!
