Snakes!

Summary: The titanaboa is the largest snake currently recorded. Now extinct, it is believed that the snake lived in the neotropical forest over 58 million years ago. This large creature was 42 feet long, and 251O pounds! Recently scientists have "unearthed" the first evidence of this creature living in the neotropical forest! This creature became extinct during a mass extinction. The forest currently contains hardly any plants, which makes scientists wonder if thats why the mass extinction occured.

Opinion: I think it is really cool that scientists can trace life back so far. Technology has really come a long way. Just by todays discoveries they can tell why a mass extinction occured! I wish I could do that. The creature seems massive, and I kinda wonder how it was found in the first place, and why the discoverer, didnt run away.
