Ratfish?

Hello everybody, long time no see!

Went to Ramenessin, NJ today to do some hunting and found this.

It’s about 1 cm across at its widest point. The texture on the bottom (or top?) reminds me of a ratfish. 

Wondering if anybody can positively ID this for me! Thank you!

Yep, That's a small fragment of chimaeroid jaw, most likely Ischyodus. Good eye!

Fantastic, thank you Carl!
