When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "ILSTRAT",
   title = "Gulfian Series --- ILSTRAT{,} Illinois State Geological Survey",
   year = "2017",
   url = "\url{https://ilstratwiki.web.illinois.edu/index.php?title=Gulfian_Series&oldid=15192}",
   note = "[Online; accessed 28-April-2025]"
 }
