These are from a very tall bank next to a river on a property that belongs to a relative of mine. I've found a number of things I think are fossils here over the years. By far these things are the most common, my wife and I found these just by looking around the bottom of the bank for about 15-20min. I have some other types of fossils from here that I found as a kid years ago that I packed away somewhere. I may post later if I find them.

Oval cross section, 2-4cm wide and shiny somewhat flaky exterior and noticeable ridges/bumps evenly spaced along the length. In the 4th and 5th photo you can see some that are still partially embedded in soft stone/hardened clay.

Are there any tricks to getting around breathing out through your nose during underwater kick in backstroke? My underwater kick is faster than my swimming and I'd like to take full advantage of my walls in backstroke like I do in Fly but I just can't seem to figure this part out, if I let the water go up I just panic and start breathing out again. I've thought about a noseplug but I feel like it would disrupt my breathing during the above water portions of my race.
