The oldest described fossils of the extant spider family Araneidae (Araneinae; gen. et sp. indet.), the extant genus Orchestina (Oonopidae; O. sp. indet.) and the new fossil genus Palaeosegestria (Segestriidae; P. lutzzii gen. et sp. nov.) are presented from Upper Cretaceous amber of New Jersey. The known fossil range of the extant family Araneidae is extended approximately 50 myr from the previously oldest described araneid from the Middle Eocene oil shales of the Messel pit in Hesse, Germany. The fossil range of the extant genus Orchestina is also extended 50 myr from the previously oldest described specimen in Eocene Baltic amber.
