Lots of ordinary things lately at Etobicoke Creek and Joshua Creek. Of course, when I began hunting in April 2019, I couldn't imagine finding such treasures, but there you have it. At the former location, we seem to have fun finding "How many decent-size orthocone nautiloids can fit on one rock," and the number appears to be 10 or 12 in some cases ! We also seem to be able to find snakes when we lift rocks, which can be disconcerting. Recently I noticed some unpromising "wavy surface" rocks, but they had a layer underneath with branching bryozoan fragments. Turns out, there are lots of them, and some are the largest chunks I've ever seen. So today I was out in the rain, getting muddy. I had to leave lots of great rocks...they were reasonably heavy chunks. Tree roots along the creek had split up the shales, pushed some promising rocks through to the forest floor, and dumped lots of slabs onto the creekbank. When I get some of these rocks cleaned up, I hope to post some pictures. Meanwhile, here is a group of recent finds.

With fall just around the corner, I was able to get in a hunting trip with my friend Jeffrey P, to the wilds of upstate NY: Specifically, the Deep Springs Road Site, in Earlville. I met up with Jeff at our usual meet up place, and time, (6:00 am at a park and ride near Jeff - about an hour away from my home.) and loaded his gear into my vehicle. Off we went. We enjoyed some very nice scenery, once the morning fog lifted. Hills, streams, farms, and wildlife. We both saw a bald eagle flying by, and some turkeys, chickens, and a deer or two. After a stop for gas and some food in Roscoe, NY, we headed up to Earlville. It was, as usual, a good ride, punctuated with some great conversation, and some interesting music. We arrived at the site around 9:50 AM. The place looked like it had be worked quite a bit, with large areas of rubble from other people's digging. The weather cooperated nicely, - it was beautiful, with temps in the low 70's, and we enjoyed sun and some cool breezes. We got to work quickly, and finds came in drips and drabs. We both made some decent finds, (pics to follow.) Jeff getting ready to start the day. We hunted until about 5 pm. With a 4.5 hour drive ahead, (for me) we got on the road. A brief stop at everyone's favorite Scottish Restaurant, and a quick stop for gas, we finished the day out with more good conversation and music. Traffic was great until after I dropped Jeff off. I spent about 25 minutes in stop and go traffic on I-84 through Southbury. I got home at around 9:45 PM. Jeff is such a great guy to hunt with. Informative, supportive, knowledgeable, and often quite funny. I always enjoy hunting trips with him. Thanks again for another great trip, Jeff. Please feel free to add your finds here, Jeff. Hope you enjoyed the report and finds. Until next time, Kind regards,

Not a huge piece of my collection but still neat. The fine details of these marine animals are often lost to the ages but every once in awhile you find a few pieces that catch your eye. I was digging through my collections curious about those fossils I found when I first started collecting. Came across this little invertebrate nugget. It is worn but the color and how it hugged the matrix was attractive. Taxonomy: Animalia; Bryozoa; Ectoprocta; Gymnolaemata; Trepostomata; Amalgamata; Monticuliporidae

Goniatite, Cephalopods, Bryozoans after rain
Rocky Stoner posted a topic in General Fossil Discussion
Hi Folks. Anxious for the rain to quit so I can start digging again. Took a walk through the garden patches and picked these up today after several nice "rinsing" rains". I hope to find more of the bryozoan plates, maybe more larger ones. Maybe you can see more than one variety in the attached pics. More to come .... I'm hoping. Kind regards,

Hi everyone, I find this tiny but well-preserved encrusting bryozoan sheet: Same piece includes not so well-preserved branching bryozoans: I understand species ID is likely impossible without more magnification, but I will be very thankful for any guesses about their order, family or genus. Maastrichtian strata, Catalan Pyrenees.

Hello. 2 years ago i got box with fossils described as Fossiles U.S.W Marvejols. I didn't get any more info about them. For me fauna looks Devonian Frasnian. Most of fossil sites in the area are Mesosoic. First specimen contains 3 different corals.( Alveolites ,Aulopora and Thamnopora ??)

Tiny Bryozoans from the Permian Fort Apache Limestone
Arizona Chris posted a topic in Micro-paleontology
Hello everyone! We just finished our study of the diminutive bryozoans we found in the Fort Apache east of Payson along the Highland Trail. As expected, they are all very small indeed and tell us once again that the environment they lived in was a stressed and sediment filled sea bottom, with little escape from the huge clouds of silt and sand raining down on them constantly. Thanks for looking, and it is with great pleasure we share this write up with you! (Adapted from our Paleo web site) For the amount of Limestone we have dissolved - now in excess of 200 pounds or so, it was surprising to only see about a teaspoon of bryozoans show up the acid fines. But this is an additional clue to the conditions which deposited the Fort Apache Limestone. As noted from write ups on previous batches of material, the amount of sand and silt mixed in with the limestone was a whopping 10%. The source of course was the Sahara like dune complex on shore with its blowing winds and large amount of muds and silts washing into the sea. The dune complex is now lithified into the adjacent Schnebly Hill formation, and forms the gorgeous Permian red buttes seen in Sedona and surrounding areas. Great for scenery, but at the time, bad for the marine fauna which had to deal with large amounts of sediment always raining down on the ocean bottom. This explains the almost complete lack of certain fossils, such as crinoids, brachiopods and corals. These invertebrates cannot tolerate large amounts of sediments raining do on on them as it clogs their filter feeding apparatus, and will not be found in such areas. Bryozoans were also filter feeders, and they are very limited in this formation, as are sponges. We encounter three types of small bryozoans in the acid fines from the Fort Apache. First, we have a branch or twig like diminutive bryozoan with extremely small pores over its surface. These are some of the smallest bryozoans we have ever seen! Second, a larger zooid type that encrusts shells and urchin spines. These have excellent detail in each zooecium. (the body chambers for each animal) And finally, fan shaped fenestrate bryozoans can be found in small broken pieces. These net like "moss animals" have some very nice fine details in the fan segments. Only a half a teaspoon of those were found, so are quite rare. Here are some representative images of the bryozoans we have found in the Fort Apache Limestone, with magnifications that vary from 7x to 45x. Fenestrate bryozoans - 7x. These fan shaped colonies were always found in tiny centimeter or less sized fragments, and never larger. But they have excellent surface details on the zooecium side. Closer view, with pin head at bottom for scale. 45x view showing small tube like pouches which contained individuals. These small tube like chambers are called zooecium in fossils and cystid for still extant living species. Every small branching bryozoan we found can fit in a half a teaspoon. Some have Y shaped branching, others are straight or tapered. A pinhead for scale is at the bottom. Some of the smallest members of this type seen here. Millimeter scale at bottom. 45x view of individual with very tiny pores. The third type was a more robust larger encrusting bryozoan. This one covers the exterior of a broken urchin spine. Millimeters at bottom. An urchin spine with a bryozoan partly encrusting its surface. The largest encrusting specimen was stained red by oxides in the silica. Encrusting type over a spine, showing detail in the zooecium. Thanks again for looking, we are now starting work on sponges we found, a very few of them, but they are spectacular in micro details!

Help planning large fossil trip in Pennsylvania
Fossil123 posted a topic in General Fossil Discussion
(Note: this was originally posted under fossil trips) Hey there! I'm sorry its been so long since I've posted on here but suffice it to say I need your help. I'm planning a six to seven day fossil hunting trip in Pennsylvania (sometime in mid august) and I need your help verifying that the sites I've picked to visit from Robert Beards guide Rock Hounding Pennsylvania are still accessible to collecting as well as coverable given my time frame. The places I'm looking at hunting are sites 27. Beltzville State Park (Outcrops on shoreline), 28. Lehighton, Lehigh Canal (Former borrow pit and outcrop),30. Deer Lake (Borrow Pit), 33. Suedberg (Outcrop in former borrow pit), 35. Centralia (Former strip mine outcrop), 38. Rockville (Former quarry), 48. Walker Lake (Hillside and unpaved road), 51. PPL Montour Preserve (Hillside, Former borrow pit), 57. Uniontown (Former quarry). Any insights as to whether or not theses sites are still accessible to collecting, weather our not you believe covering all these sites within 6 to 7 days is possible, and any other tips and tidbits of information on the sites, and or planning a large trip like this etc, would be greatly appreciated! When I go I'm planning to take notes and pictures and then, when i get back, write a few essays illustrated with pics that I will post on here! Thank you in advance, and thank you to Fossil-Hound for directing me on were to properly post this! Glenn aka Fossil123 -

Brechin, Ontario with Malcolm and the New York Paleontological Society
Jeffrey P posted a topic in Fossil Hunting Trips
The weekend of June 24th and 25th I participated in an outing with the New York Paleontological Society led by my friend, Ray McKinney to Brechin, Ontario. TFF Member Malcolm led our group into the James Dick quarry where both Bobycaygeon and Verulam Formations are exposed. These are Middle Ordovician from the Trenton Group and contain a wide variety of invertebrate fossil fauna. Also met other TFF members Kevin (Northern Sharks) and Joe (crinus). Most of the quarry is the Bobycaygeon and the very top is the Verulam- only accessible near the entrance, but I got some excellent well preserved matrix plates from there. I spent the second day combing the spoil piles. This first picture is Lake Simco by Beaverton where we stayed. Malcolm in the middle, explaining the quarry geology to NY Paleontological Society members.

A little Ordovician collecting at St. Leon and Lawrenceburg, Indiana Roadcuts
Nimravis posted a topic in Fossil Hunting Trips
To begin with I am not an Ordovician collector, but after seeing recent posts from other FF members, I decided to stop at the St. Leon and Lawrenceburg road cuts in Southern Indiana as I was making my way to North Carolina. I will post picks without specific ids, I know I have bryozoans, brachiopods, horn corals- but no trilobites. I did find 3 things that look to me to be possible Cephalopods, but could be mistaken. I also found 1 other item that I have no clue to its I'd. Any help with these last 4 items would be appreciated.

I found several mixed pieces last weekend while out in southwest Virginia; bits that had tumbled down the hillside and into the road. This was along a road that follows the Holston River, in mostly limestone/shale. One piece was filled with crinoids (stems), from tiny to pencil diameter; one had meshy bryozoan pieces and brachiopods, then there was the piece that had this. Please bear with me, I've looked online, and in my books, but since I have no idea what I'm looking for, it complicates things, and I want to learn. In both examples, the coral-looking chamber/pore sections are alongside the mesh/bryozoan-looking sections, so I'm not even sure if I'm looking for one, or two separate, organisms. I'm sure whatever it is, it's probably very common in this area, but if someone could help ID it so I'll know next time, or at least point me in the direction of what I need to research, I'd be grateful. Thank you!
