Well folks, I already did that. Back in twenty 'ought one, if I recall, right after I perfected my first time machine.
I couldn't pick just one dinosaur, so decided to kill 'em all. Used a big ol' asteroid as my weapon of choice, at a spot in Mexico called Chicxulub. Darn good dino barbeque if I do say so myself, course a bunch o' them little critters on the land just hid out underground for a bit and made out ok, same for most of the sea critters... but them big ol' dinos just burned right up...
Sorry 'bout ruining y'alls huntin' and all that... I'm all about QDM (Quality Dinosaur Management), but I reckon I got a bit carried away...
The Discovery Channel sometimes airs a special on my "huntin' trip"...
Went back a little later in time once to kill a Mastodon, just got plain disgusted reading the cave pictograpghs arguing about "tusk hunters" vs. "meat" hunters and came on back here. Same arguement for thousands of years, I guess...
I'm a great hunter and a fine fugure of a man, and that's all y'all need to know for now....
