Starfish and brittle star traces: Another fun find from the Fossil Forum archives. Some superior brittle star resting burrows, indeed. Great finds. In addition to their Missouri occurrences, those same Asteriacites brittle star ichnofossils can also be found in upper Pennsylvanian strata of Kansas--For example: in the Rock Lake Shale (Lansing Group); Stranger (Tonganoxie Sandstone Member) and Lawrence Formations (Douglas Group); and, in the Kanwaka Shale (Stull Shale Member) of the Shawnee Group. A superior reference to consult on the Kansas-Missouri brittle star ichnofossil occurrences is the 1999 technical paper: The Origin and paleoecologic significance of the trace fossil Asteriacites in the Pennsylvanian of Missouri and Kansas. 1 Link to comment Share on other sites More sharing options...
