[B&L] spinning with the dinosaurs--upper Cretaceous spiders in amber
- Spinning with the dinosaurs���spiders in Upper Cretaceous amber from New
Jersey (Arthropoda: Araneae) David Penney, 2001. Abstracts. XV
International Congress of Arachnology, South Africa, 127.ABSTRACT
The oldest described fossils of the extant spider families Segestriidae,
Oonopidae, Oecobiidae, Dictynidae and Linyphiidae, previously known from
the Tertiary, are presented from Upper Cretaceous amber of New Jersey.
The third and oldest known specimen of the fossil spider family
Lagonomegopidae is also described and provides further palaeontological
evidence of a common Laurasian fauna. The extant genera Segestria and
Oecobius are taken back a further 52 and 69���74 my respectively in the
fossil record. These fossils predict the presence of the Caponiidae,
Tetrablemmidae, Orsolobidae, Dysderidae, Hersiliidae, Eresidae, Pimoidae,
Scytodoidea s.l., cyatholipoids, theridioids and symphytognathoids in the
Cretaceous. The fossils extend the known geological range of extant
spider families through andbeyond the end-Cretaceous extinction.
