Proboscidea tooth

[Seeigel]

Am looking to buy this tooth. However I am not sure if the seller has classified it as the right species. I am quite obsessed with the history of our elephant but I find it hard to tell because it is in pretty rough shape (also i really want it to be true so looking for a second opinion). Any experts on Proboscidea? Will tell what species the seller id it as if interested but not right here because i dont want to sway any opinions.

 

found in Mainzer Becken, Germany

12,5 cm (about 5 inches)
