WI-fossil-guy Posted May 24, 2019 Share Posted May 24, 2019 (edited) New member here. You all have been most helpful so far, thanks. These requested possible fossil ID were collected from a drained lake bottom in western Wisconsin (Vernon County). It is not soft like sandstone. There are two different items. The longer item (#1A-D)is shown on all four sides. The shorter item(2A&B) is shown just front and back.

Wrangellian Posted May 24, 2019 Share Posted May 24, 2019 They do look stromatolitish to me, but I've been wrong/fooled before. BTW not all sandstone is soft! Welcome to TFF. 1 Link to comment Share on other sites More sharing options...
hemipristis Posted May 25, 2019 Share Posted May 25, 2019 Certainly looks like it. Try adding a few drops of vinegar to test if it's limestone. 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
ashcraft Posted May 25, 2019 Share Posted May 25, 2019 Looks like one to me. Stromatolites can also be found in sandstone. If the sandstone gets altered to flint, then you have something worthy of cutting. Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...
