Jurassic Jim Posted June 11, 2011 Share Posted June 11, 2011 Here is the next set. Several of these I have no good identification to provide. If anyone has ideas I would love to hear them. The first is planolites, good ole worm burrows. Trichophycus maybe? If so this is interpreted to be a arthropod burrow. It has long ridges that run the length of the burrow. These two I like a lot. Really great sweeping pattern from I assume some kind of arthropod that then dives down into the matrix. The hole actually goes through and comes out the edge of the matrix. I have no idea about this one. To me it resembles a jellyfish in appearance, there is a bit of a mound with very fine trailing striations extending out from it. It almost has 2 lobe symmetry...but anyway I have no clue. Part 3 to follow. Link to comment Share on other sites More sharing options...
