Mysterious sea Creatures

One of the things we collected a lot of from the strand lines was a variety of sea creatures.  There are a lot of pieces of what we thought (in the field) was gut, which is a useful raw material.  Now that we’ve gotten them into the lab, we think most of it is some sort of marine worms.  There are also a variety of other small marine creatures (plants or invertebrates–they have lost their orignal colors) and mollusks.

Marine worm? from 300-400 AD
Another sort of sea creature
Some sort of seaweed?
Maybe some type of sponge-like creature?

Obviously, I know a lot more about mammal bones & teeth than these things.  So we’ve sorted out a bunch, and Claire will take a couple of each type to Fairbanks, along with the shells. With any luck, we can get some IDs.  If we’re really lucky, the species in question will turn out to have fairly narrow habitat requirements, and we’ll know something about what the ocean was like near Barrow when the big storm happened between 300 & 400 AD.

If you happen to recognize any of these, please let me know what you think they are.  If you know anyone who might be interested in these creatures, send them my way.  The “worms” are very well-preserved, and still flexible.  It occurs to me that it might be possible to extract DNA from them (and maybe some of the other creatures as well), which would be a pretty rare opportunity.
