Mioplosus_Lover24 Posted April 8, 2019 Share Posted April 8, 2019 I made this chart about the Greenriver formation, and I was making sure I had everything right. I know I am missing 3 fish, but I could find no evidence of predation or them preying on any other fish. My conclusion was that Amia was the super predator! 3 "Life is too complex for me to wrap my mind around, that's why I have fossils and not pets!"

Fossildude19 Posted April 8, 2019 Share Posted April 8, 2019 Good work. However, ... I understand the gist of what you are doing, but, ... your presentation is a but muddy for me. I think you need to label the fish pictures. Then show via thicker arrows coming from each predator to each prey fish of that species. It is a bit confusing though, with all of the arrows. Maybe having a list of the fish, on one side, and the names of the fish/ they ate to the right or left... 3 Tim - VETERAN SHALE SPLITTER VFOTM - APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Fossildude19 Posted April 8, 2019 Share Posted April 8, 2019 Also, the other species of fish should probably be included, as they were at least prey for the others. 1 Tim - VETERAN SHALE SPLITTER VFOTM - APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Mahnmut Posted April 9, 2019 Share Posted April 9, 2019 Nice work! I know predators are often more fascinating than their prey. Still it would be interesrting to arange the species by trophic level, that means plant eating fish in one level, those that eat only planteaters next, then the ones that eat those. Many species ocupy more than one level, depending on their luck in beeing eaten or not. the top predator is the one that eats most and is eaten least. Often the abundance of species drops when going from low order consuments towards the top of the foodchain, would be interesting if this holds true for these fish. According to this, your three missing fish should be among the most common. (or maybe there is a collection bias because prdatory fish are more interesting to the collector?) best regards, J 2 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...

Had to make assumptions on Asineops as there are no living relatives, but based on the fact they had teeth they most likely wouldn't have passed up a Knightea!
