Just got back from a 5 day trip to western NSW where we visited a number of sites, some of which we had not visited before. Will post more photos and information over the next few days as I have a lot to photograph, but here are some field shots from day two (our first collecting day)...

 

Our first site was located near Grenfell and is known for its excellent Devonian fish fauna, including placoderms and sarcopterygians. While not as well preserved as the nearby Canowindra site, these are collectable which is a start ;). We were only given a vague site on a hillside located on private property, so once we had permission to access the site the next issue was finding where the fossil bearing layers were. This involved climbing a very steep hill and breaking open any rocks we saw, and after finding evidence of placoderm plates the next task was to figure out where they originated. A number of fossil bearing layers were found and it seems the material is very extensively distributed, presumably occurring throughout the surrounding hills as well. Here are some photos of one rock face we worked and the terrain -

There were a number of rocks with exposed fossils on them, for example this one which is covered in ornamentation from placoderm plates.

And here is a field photo of a partial Sarcopterygian(?) jaw, my thumb is on the left for scale.

An Eastern tree dtella (Gehyra versicolor) my friend found while digging -

And a tiny fish spine -

After a few days of checking out some other sites without much success we went down to Yass for Silurian trilobites and other marine invertebrates. Here are a couple of unidentified Odontopleurids. Will post more photos of our trilobite finds soon. Any ideas @piranha?

The odontopleurid meraspids are tricky ... the pygidial spines are absent on this one mail?url=http%3A%2F%2Fmail.yimg.com%2Fok%2Fu%2Fassets%2Fimg%2Femoticons%2Femo71.gif&t=1595263093&ymreqid=23281213-8dc1-3cff-1ccd-13000301a800&sig=8xly.Lp.1FItZywUjIu2cg--~D

 

 

I would label this one Ceratocephala sp.

And excellent, thanks for that. I appreciate the help as always!
