’n Groot verskeidenheid spesies het in die K-Pg-uitwissing omgekom. Die bekendste slagoffers was die nie-vlieënde dinosourusse. Ander organismes is egter ook erg geraak, soos [[soogdier]]e, [[voël]]s,<ref>{{cite journal | author = Longrich N. R., Tokaryk T. T.

Die verwoesting wat deur die uitwissing veroorsaak is, het egter ook evolusiegeleenthede geskep. Ná die voorval het baie groepe skielike en groot veranderings ondergaan en is nuwe lewensvorme geskep wat die ekologiese nisse gevul het wat deur die uitwissing leeg gelaat is. Soogdiere het veral in die Paleogeen gediversifiseer<ref name="Alroy, J. 1999">{{cite journal | author = Alroy J | year = 1999 | title = The fossil record of North American Mammals: evidence for a Palaeocene evolutionary radiation | url = | journal = Systematic Biology | volume = 48 | issue = 1| pages = 107–118 }}</ref> en nuwe vorms aangeneem soos perde, walvisse, vlermuise en primate.
