At the very least, these are incredibly preserved fossils, but the view put forward is they are fossils preserved from the time of the asteroid impact. https://www.bbc.co.uk/news/science-environment-61013740

At Tanis, scientists studied the remains of three sturgeons and three paddlefish, using in particular high-resolution X-ray tomographic analysis from the Grenoble European Synchrotron (ESRF). They first established that the fish had indeed perished in the seiche episode, which was accompanied by a rain of glass spherules... https://www.cnn.com/2022/02/23/world/asteroid-dinosaur-extinction-spring-scn/index.html The research is described in a paper published Wednesday (Dec. 8) in the journal Scientific Reports.

Found 8 Aug 2013. An extremely rare starfisht, it was 1 of less than 10 complete specimens ever found at that time. It was found in the sand layer of the Rocky Point member of the PeeDee. This layer contains abundant Flemingostrea subspatulata among other oysters along with Hardouinia mortonis and kellumi echinoids. This starfish was invertebrate fossil of the month in 08/2013.

The exact place where the asteroid impact theory was born
Italo40 posted a topic in General Fossil Discussion
Dear members, today I want to talk about how one of the most widely known theories of the geo/palaeontological world was born. I'm referring to the the theory according to which an Asteroid Impact caused the end-Cretaceous extinction. Last weekend I have visited the exact spot where, essentialy, this theory was first developed. It is the K/Pg Boundary in the Bottaccione section in Gubbio, a medieval town that lies on the Appenine Mountains, in the heart of Italy (see the red arrow). A widely distributed rock that makes up these mountains is the pelagic limestone sequence of th -
From the album: Invertebrates and plants(& misc.)
Debris, including micro glass "beads" from melted earth ejected into the air, from the KT boundary burn layer. Garfield county, Montana, Hell Creek formation. Late cretaceous (duh) *i added "misc." to this album because this didn't fit anywhere, and I thought it was really cool and should definitely be included somewhere. **There could even be vaporized dinosaur material as part of the glass and melted debris included. There definitely was plenty of it, but I guess realistically, unless it became evenly spread into the atmosphere and airborne debris, this is -
