Can anyone help with verifying authenticity?

I found this shark tooth at an estate sale and picked it up. I was told it was found during a trip to Morocco. I think the owner must've been a rock collector or a geologist as there were hundreds of gems, stones, fossils, and similar things from all over the world. I didn't pay much, so I won't sweat it if it's a fake. However, if it is authentic, can anyone help ID the species? It's a little over 2 inches long.
