Hi everyone! Holidays mean more time to photo and post. As previously mentioned in my previous post, I am finding a lot of fossil impressions and voids in chert and mudstone on a small artist residency and farm in Kingsbury, Texas, in Guadeloupe County. And some petrified wood. Most of the casts I find are pelecypods and some gastropods; however I am finding some other stuff, some of it total mystery. This time I will post the mystery items first. Let me know your thoughts! This first mystery (3 views) has tight incised lines around the darker shape - most evident in central photo. The next item, below, has lots of impressions. The closeup on right shows a spiral on left side, is that a worm, or a gastropod internal cast/mold? I think the horizontal cavities on right of closeup are some kind of coral? Here's some coral ... or petrified wood? (two images Photoshopped together) And also...the below is super interesting...at first I thought it was just a chip, or a shell impression. But starting to think insect wings! At first I thought this could be a bryozoa (left photo below), but I think it is more likely a worn pelecypod impression, re like the typical one on the other side other rock (right photo). And here's some pet wood, various types And bone? Or coral? I keep thinking bone because of smooth sides.
This weekend I went on another fossil hunting trip with my dad. We went to a place called Bacchus Marsh which is around 65 km east of Melbourne. Here we went looking for Tertiary plant fossils such as Laurus and Cinnamonum. The site was a creek bed under an old bridge. The bridge was located next to the Western Freeway which connects Bacchus Marsh to Melbourne, and extends north to south, eventually emptying into the Werribee river (about 2km away). The creek also goes under the freeway through two tunnels and you can look for fossils on both sides of the freeway, but the side near the bridge had the best rocks. The rocks we looked for were Ferruginous sandstones which are late Paleocene (59 million) to Middle Miocene (14 million). The creek was dry and it didn't look there had been water in it for a long time.
