Since Leisman’s primary research interest was Carboniferous coal ball flora and ecological studies, he, his students and his collaborators collected numerous coal balls.
The following is a list of the coal ball numbers we know exist (or existed) along with what is known about the location/locality that they come from. This list does not include coal balls that Leisman or his collaborators studied while on loan to them. Please note that if a publication lists the total number of coal balls studied from a particular locality without listing their coal ball numbers they are not on this list, but are listed as part of the associated coal balls on the publication specific page (you can find a list of publications on our page Leisman Publications). Also note that some entries in the table are ranges of coal ball numbers that had to have existed based on the numbers of the located specimens derived from coal balls.
Before any sorting, we list the coal balls and coal ball ranges numerically. The columns are sortable by clicking on the heading. The first click to a heading sorts them alphabetically (A to Z)/numerically (1-25). The second click to heading sorts them reverse alphabetically (Z to A)/numerically (25-1). The third click to heading brings back to original sort order.
If you are aware of additional coal balls, know more about the locality the coal balls or know of the fate of specific coal balls we would encourage you to add what you know in the Collection Forum or contact us.
