The bottom cassette is the old one of course. I have never replaced one before and I clear bought the wrong kind (top pic).
Is there a name for these teeth that I need to be looking for when buying?
It is a 12 speed mtn bike cassette.
My bike is now out of commission until I can get the part I need. Thanks in advance.

you are looking for a hyper glide (HG) cassette. looks like you purchased a microspline
You bought a microspline. You need a HG compatible cassette.
Cassettes are often referred to by the feehub body or driver (the part you slide your cassette on to). There are a few different standards (for a few reasons). HG has been around the longest. You need a cassette that is HG compatible. It looks like you bought one that is microspline which is another standard. If you are riding SRAM parts, an NX or SX cassette will work. Easy mistake to make. Also, you can not use a XD cassettes as well as that is a different standard.
