In canids such as Canis latrans, the upper carnassials (the large pointy cheek tooth) are the fourth premolars (P4). The lower carnassial teeth are the first molar (m1). It's easy usually to distinguish between canid upper and lower carnassials.
The upper carnassial (P4) in canids has three roots... I believe that the Dire Wolf lower carnassial M1 is the other best option for the carnassial fragment I found. I considered the Dire Wolf M1, and thought the Jaguar p4 was a slightly better fit. Mostly I see the "peak" of the Dire Wolf carnassial to be centered of slightly more over the larger root than the smaller root.
carnassial teeth in cats, Hi There, I've been holding onto this for a year or so waiting to get it ID'd .. always suspected it was a tapir tooth partial but that was before I stumbled upon a few Dire Wolf carnassials with similar breaks. Is this possibly half of a Dire Wolf Carnassial tooth ? @Harry Pristis This was found... Dire Wolf Carnassial Tooth ?
carnassial teeth in cats, - Fossil ID - The Fossil Forum Unknown Carnassial Tooth And Unknown Jaw Fragment. By justinb in Fossil ID I just went through the process of trying to get a cat molar identified and even the feline experts weren't willing to offer an even remotely positive ID based on the molar alone. Here's a jaguar jaw with the tooth in question; notice the crown of the carnassial is 23mm (0.9") long.
