Wrightsville Beach Fossil

Recommended Posts

Anchiornis

On my recent visit to Wrightsville Beach, NC, about 2 weeks ago, I found the shore scattered not only with large amounts of the usual shells, but also large, rocky chunks of the seafloor. Among them, I found large granite blocks and pieces of seafloor containing nondescript bivalve impressions. However, I also found this strange fossil(?) lying on the shore (although I did not collect it). What is it? It looks like a piece of shipworm-infested wood, although it felt pretty hard in texture. Could it be petrified shipworm wood?IMG_6323.thumb.JPG.3ced2b015387ad0cd5a0adaeaf6e0262.JPG

Serpulid worm tube mass I think.

Wow, thank you! Is there any evidence for this being a fossil, or is this a more recent one? And if it is a fossil, what rock formation did in come from? I've heard of Oligocene outcrops offshore from Wrightsville; could it be from those?

I think that it's probably recent, but someone from the area would probably know better.

If the larger circular shape in the upper right can be identified it could be helpful in determining this.

The colony may have formed a mold around something, or it may have been bored by bivalves in the same manner as shipworms do wood.
