Approximately 1/3 of interplanetary dust particles (IDPs) and some primitive meteorites have large excesses in D and/or 15N compared to terrestrial materials. Constraints on the nature and origin of the carriers of these isotopic anomalies are reviewed. Special attention is given to a recently discovered extremely D-rich cluster IDP.
