Wikimedia Commons has media related to 1981 in paleontology.

Paleontology or palaeontology (from Greek: paleo, "ancient"; ontos, "being"; and logos, "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils.^[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1981.

Remarks on newly named birds

Palaeopteryx thomsoni Jensen, 1981. is most probably not a bird but perhaps a small dinosaur, it is best treated as a taxon non avium.
Plegadis pharangites Olson, 1981. is a new name for Plegadis gracilis Miller et Bowman, 1956, preoccupied by Plegadis gracilis (Lydekker, 1891), described as Milnea gracilis Lydekker, 1891 and transferred to the genus Plegadis Kaup, 1829 by Cheneval, 1984.
