    multicolor spots that 'bloom' on wood?

    Going through my bucket of unknowns and no better way to describe this. Found in creek with mix of Cretateous and alluvial deposits. Originally thought it was wood, not so sure now, I've never seen these spots before that look like they're floating. So tiny hard to get clear pics of the white spots that look like a flower opening and some of the spots appear to be holes at the surface. Must be biological in nature I'm thinking but what? It's pretty whatever it is.
  2. I recently published a paper describing how biological cells and soft tissues preserve in ancient vertebrate fossils, combining the two major hypotheses by Dr. Mary Schweitzer and Dr. Jasmina Wiemann. Apparently, a biology professor at the University of Akron made a video on it, and it explains the paper rather nicely for the layman. His comments on it start at the 14:50 mark, before that he deals with some inaccurate claims made about soft tissue preservation by others: https://youtu.be/ViCJtaePtzY
  3. We found a very unusual rock or fossil in a load of bull rocks and I'm wondering if any of you can offer any insight. There are lots of limestone deposits, caves and fossils in our area, but this specimen was in a load of bull rocks used for landscaping, so probably from somewhere in central Texas. It's about 15 CM long by 5 cm wide by 2 cm thick and is oddly structured. There are various layers that look biological in origin to me. The surface I'll call the 'top' resembled onyx in color and translucence with a 'bubbled' surface similar to a piece of bacon. In some areas, this layer appears to have been worn through. This layer looks like what I'd imagine 'fossilized fat' to look like. Then come several layers of various colors (buff, tan, reddish) and thicknesses (2 - 4 mm) that appear to have a cellular structure, with tiny walls and pockets. These remind me of gills on a crab or lobster or perhaps petrified wood. The surface I call the bottom resembles our area's limestone but is rough and pock-marked. Any ideas?
