IIRC Lance was on the shore of the WIS, so you'd expect the marine species such as Belanstomas and several of the cartilaginous fish may have been more common there, while some of the freshwater species could have been scarcer. There also may have been brackish water species, and more marine species that would appear at Lance but not HC. Of course, this is all conjecture, I haven't read any statistics.
Most of the papers I read didn't come with size estimates unfortunately. Belonstomus could reach a meter in length. Living sturgeons are very large fish, so these species also have the potential to reach large sizes. The teleosts are all very small. The others gave no indications. They'd just have to be based on modern bowfins, gars, etc.
