Determining leather type of a jacket

[Dortreo]

Hi all, I’m still fairly new to leather jackets and am wondering if anyone has ever published a how to guide to determining the leather type of a jacket. I recently purchased my first Thedi but the seller didn’t know what type of leather it was. Is there a way to tell from the grain? As far as I can tell, it’s probably horsehide or steerhide. Not deer. Maybe bison?

Yeah, I keep reading about grain pattern but have no idea how that actually works as it depends upon where the leather's from and how it's been treated.
