Riversleigh expedition 2015

01 August 2015

The 2015 expedition to Riversleigh produced some great results.

A multidisciplinary team from UNSW and the University of Melbourne undertook a variety of field activities there from 2-9 July 2015.

Geochemical, mineralogical and palynological analyses will be conducted on samples collected from multiple locations in order to better understand the geology and ages of the Riversleigh Cenozoic deposits. Prof. David Cohen employed the Handheld XRF Analyser (aka. Mr Thingy) to measure the geochemical components of outcrops, including those along a number of transects.

More of the remote "New Riversleigh" area was explored, further expanding the known extent of Cenozoic deposits in the region. Previously unknown caves were found and earmarked for exploration and sampling in the future.

Cenozoic deposits within the Riversleigh World Heritage Area were also surveyed and a number of new fossil deposits were found including Wailing Chicken, Joy's Diamond Celebration, Heather's Happy Hump, Jane's Fabulous Fossils and Bat Outta Hell Sites. Large numbers of fossils were found across an extensive area at Ben and Evan's Playground Site (BEP), including parts of the jaws, skull and skeleton of more than one very large crocodilian.

Fossils were collected from known sites including Bok's Cordless Triumph, Jon's Dating Madness and Golden Steph Sites. Dunsinane Site was revisited and more enigmatic plant and invertebrate-bearing fossil material was recovered from there as well as fossil vertebrates.

Another productive field-trip thanks to the efforts of the research team, students and volunteers.
