Summary:Throughout time, evolution has shaped our world. Scientists have been studying this subject for many years and have uncovered many different species that have evolved. Scientists are now saying that they have found a “missing link” in the evolution of seals and walruses. They have recently found the skeleton of a web-footed, otter-like creature. They discovered that this “newly discovered” creature was developing away from a land life. One expert stated that it fills a gap in the fossil record. They are not direct ancestors of the seal family but are from a different branch of mammals. These creatures are 23 million years old. The fossil of this interesting find was found on Devon Island in the Canadian Arctic. The creatures name is Puijila darwini, meaning "young sea mammal.”
Why I chose this article: I chose this article becasue I enjoy learning about new fossil discoveries. I found this article extremely interesting, because I thought that it was very cool that scientists finally found the information that would close the gap in the fossil record, that they were looking for. I think that it is also very interesting that the newly discovered mammal was not a direct ancestor of the seal family.

Alexa-
Great job! I love otters. You did great summarizing the article and getting the key points. I thinks it very interesting how scientists found this new fossil. If you think this is interesting have you heard about the whole fossilized site over at LACMA where they were building a parking lot? Its very similar to this except that they found lots of plants and insect fossils as well as animals.

Alexa,
This article is so cool! I love to learn about new fossils scientists find, and i haven't been finding anything interesting and new lately; so this was cool to learn about and i guess we both got caught up on learning the latest news!
