Then there is Bob Carroll, whose Oklahoma trilobites exemplify excellence by all measures. Bob should be pretentious and arrogant, but he is not, should be proud, and he is. Those who acquire a Bob Carroll work of art should feel lucky, which they are. The personalities in the Paleontological Supply business are very diverse, and sorry to say, a tangible minority are not so pleasant. Some people can be, according to our research, cut throat to the point of masochism. Among this heterogeneous and motley cohort, Bob stands out as a gentleman and a gentle man, affable and intelligent, who abides Dirty Harry’s edict to, “know his limitations”. Bob and Linda Carroll own and operate Black Cat Mountain Trilobites (DBA Carroll and C Enterprises), based in Clarita, Oklahoma. The shop and prep lab is located on prime real estate directly across from the Clarity post office.
