Scientists are working diligently to uncover the mysteries surrounding the timing and causes of ice age mammal extinctions in Southern California. With the help of the National Science Foundation (NSF), researchers are delving into the past to understand why certain species disappeared during this crucial period in Earth’s history.

During the ice age, which occurred thousands of years ago, numerous large mammals roamed the land. However, many of these magnificent creatures mysteriously vanished from Southern California. Scientists are now focusing their attention on unraveling the timing of these extinctions and the factors that led to their demise.

Through extensive research and analysis, scientists are piecing together the puzzle of these ice age mammal extinctions. By examining fossils and studying the geological record, they can determine when these extinctions occurred and identify the possible causes.

One of the key factors scientists are investigating is climate change. The ice age was a time of significant climatic fluctuations, and these shifts in temperature and precipitation could have had a profound impact on the survival of ice age mammals. By studying ancient climate data and comparing it to the timing of the extinctions, scientists hope to uncover a possible correlation.

In addition to climate change, scientists are exploring other potential causes for the mammal extinctions. They are examining evidence of human activity, such as hunting and habitat destruction, as well as the influence of other species. By understanding the complex interactions between different factors, scientists aim to gain a comprehensive understanding of what led to these extinctions.

The National Science Foundation (NSF) plays a crucial role in supporting this research. Through funding and resources, the NSF enables scientists to conduct in-depth studies and gather essential data. This research not only helps us understand the past but also has implications for our understanding of present-day extinctions and conservation efforts.

In conclusion, scientists are dedicated to uncovering the timing and causes of ice age mammal extinctions in Southern California. Through extensive research and analysis supported by the National Science Foundation, they are unraveling the mysteries of the past and gaining insights into the factors that led to the disappearance of these magnificent creatures.


1. What is the ice age?
The ice age was a period in Earth’s history when large parts of the globe were covered in ice and experienced colder temperatures.

2. Why did ice age mammals go extinct?
There are several factors that could have contributed to their extinction, including climate change, human activity, and interactions with other species.

3. How do scientists determine the timing of these extinctions?
Scientists examine fossils and study the geological record to determine when these extinctions occurred.

4. What role does climate change play in these extinctions?
Climate change during the ice age, including shifts in temperature and precipitation, could have had a significant impact on the survival of ice age mammals.

5. How does the National Science Foundation support this research?
The National Science Foundation provides funding and resources to scientists, enabling them to conduct in-depth studies and gather essential data for understanding ice age mammal extinctions.
