Carbon has been recovered from Chicxulub ejecta in several forms:
relatively amorphous elemental carbon, spheroidal soot-like particles and impact-produced diamonds. The soot and elemental carbon have been recovered globally, while diamonds have only been recovered from North American K/T sites. Soot may have played an important role in any extinciton scenario (see below). At the outset, I should point out that the occurrence of impact-produced diamond in Chicxulub ejecta is very strong evidence for an impact, and while [Tom] Van Flandern's comment cites them as such, his statement that "The diamonds found at the K/T boundary are confirmed to be of extraterrestrial origin, not shock-generated or terrestrial" is inaccurate.
