RandyB Posted May 29, 2019 Share Posted May 29, 2019 https://www.sciencenews.org/article/50-million-year-old-fossil-captures-swimming-school-fish Avid fisherman here, so this one piqued my interest. Not sure I buy into the collapsing sand dune theory of how the fish were (mostly) preserved in swimming orientation, but I found the repulsion/attraction discussion intriguing as i have seen that behavior by menhadden countless times while fishing in the Atlantic. Its easy to assume extinct animals acted similar to their modern cousins, but rare to see behavioral proof. The abstract for the paper is here: https://royalsocietypublishing.org/doi/10.1098/rspb.2019.0891 3 Link to comment Share on other sites More sharing options...
jpc Posted May 30, 2019 Share Posted May 30, 2019 I have fish mortality plates form the same layer, some are random, some are unidirectional. I think the sand dune is so incredibly wrong. there is NOTHING n the geology that suggests sand dune. Link to comment Share on other sites More sharing options...

Al Dente Posted May 30, 2019 Share Posted May 30, 2019 Quote from the article- “I can’t picture a three-dimensional school of fish sinking to the bottom and maintaining all their relative positions,” Dr. Plotnick said. “That makes no sense to me.” I think current alignment makes more sense.
