help needed! colonial & fossils

[ATpro5]

Hey everyone! This is the 6th flat button I've pulled from this site. Between me and three others over 50 have been found. Even a GW button. This one is around the size of a quarter and says rich orange on the back. The reason I'm posting is because it has some kind of symbol on the bottom like a star or sun burst. Hard to explain. Is this a makers mark? Ooh and also found these fossils today! Can anyone tell me what they are?

Is the fossil wood or bone... That's what I'm wondering. The other looks like some kind of bark to me. What y'all think

Your second pic at the top looks like a broken clay tile.

Your brass 1-piece flatbutton has one of the typical British generic "Quality-rating" backmarks. Because your British-made brass flatbutton's backmark is written in indented lettering, and was dug in the USA, it dates from sometime between 1810 and the 1830s. (Importation of British-made flatbuttons into the US had ended by about 1840, because American button-makers had become capable of mass-producing that type of button.)

The meaning of the little "sunburst" design at the bottom of the backmark is unknown -- it may simply be decorative, like other non-letter/non-number "characters" (stars, asterisks, dashes) in backmarks.
