Catastrophic Quaken: rock/flying, rock/dark, or pure rock due to the aggressive nature and how it's a Boulder in the Boulder class.

Crimson Goregutter: I want to say rock/fighting due to the tail, rocky bumps on the back, and antlers. Also the coloration and protective nature. The crimson Goregutter was designed as a prehistoric creature. Most of the fossil mon are rock type and the prehistoric Koridon is part fighting.

Eruptodon: rock/fire for obvious reasons.

Grapple Grounder: Ground/dark or ground/flying or pure ground for the name and mercilessness.

Groncicle: rock/ice for also obvious reasons.

Gronckle: pure rock, rock/flying, or rock/ground due to inherent rocky-ness and Arial mobility.

Hotburple: pure rock or rock/ground for resemblance of the Gronckle but slower and lazier.

Sentinel: rock/flying or rock/ghost for statue like body, STAB air slash, and roll of protecting Vanaheim and its residents.

Shovelhelm: ground/flying or pure ground for being trained for construction.

Snafflefang: all I got is pure rock or rock/flying for bulkiness and rock eating.

Thunderpede: rock/fighting or pure fighting for coloration, large forearms, and lack of an exoskeleton.

Whispering death: ground/dark for cave dwelling, aggressiveness, digging capabilities and just by looking at it. I can probably also have earth eater.

Screaming Death: a mix of ground dark and dragon for the same reasons for the whispering death plus the legendary status.
