I found this stone with some unknow pattern in the Kalvsjøen formation, Oslo field (late Katian, in late Ordovicium). Can it be two nautiloids or alge? It is some small gastropods there too. The length of the longest "nautiloid" is about 7 cm.

I wonder if this is some animal or just a crystal formation. The surface is extremely smooth, when I touch it with my finger. The formation is from Late Ordovician. Pict. 1 Pict.2 Pict.3 Pict.4

Whetstone gulf & Pulaski formations in northwestern NY
Nautiloid posted a topic in Fossil Hunting Trips
Last fall I went on a fossil hunting trip to a creek in Adams, NY. Along this creek were exposures of the Whetstone Gulf and Pulaski formations. There were many different layers, each with different fauna. Some layers were barren, while others had many species. Some of the most common fossils were cryptolithus and triarthrus trilobites, as well as brachiopods, bivalves, gastropods, ostracods, and straight shelled nautiloids. Some layers contained pyrite and some of the fossils in these layers were partially pyritized. (Including some of the trilobites!!).- 12 replies

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

Conularia formosa (Miller and Dyer, 1878). Specimen with a positive and a negative counterpart (matrix). Found while smashing a limestone layer at Mimico Creek, Toronto, Ontario. The matrix of the Conularia has the negative on it, as well as bryozoan bits. Bibliography: Ontario. Department of Mines. The Stratigraphy And Paleontology Of Toronto And Vicinity.

I was reading a book about fossil fishes and there was a chapter dedicated to sharks and their cousins. Apparently there were chondricthyan scales found in the Late Ordovician and Early Silurian rocks. Since I hunt the Late Ordovician Georgian Bay formation in Toronto, Ontario and various Early Silurian formations in Hamilton, Ontario, what are the chances of me coming across these scales? Should I keep my eyes open and what should I look for?

I am a mineral and fossil collector and an amateur astronomer and my email is rocksnstars, so rocks collected that include a star shape are special. Most of the ones I have are the crinoid stems with star-shaped centers. This is the first time I've seen anything like this. I believe I have met the requirements of providing a good photo with a scale, and I know the period is Late Ordivician. I tagged Ohio because I think that is where it is from, but it is possibly Indiana, however BOTH sites are the SAME period and well known. I collected the two places the same day, and unfortunately dur

What a haul! Rare goodies from the St. Leon roadcut, Indiana. (Trilobites!)
FossilSniper posted a topic in Fossil Hunting Trips
About a month ago, I headed out on two fossil trips to the well-known St. Leon roadcut in Indiana. I was hunting in the Liberty formation (late Ordovician) with the sole goal of finding some nice trilobites (which I definitely achieved!). Along with multiple rare trilobites, I was able to find some excellent examples of other fossils. The spoils were totally awesome, and I am itching to go back. I hope you enjoy. Best for last. -
The first major event to wash the creek was the nasty February winter we had in the city. Let's recall the ice that melted and went down the creek back in March. Then fast forward to June. I believe the city had rain during the first 2 straight weeks of June in which I remember seeing many creeks being flooded continuously for several days. Then gradually the rain stopped, I waited for some time to give the creek's water level to drop low again, and that's when I set off to visit the ravines of Mimico Creek.

Lituites Fossil China TIME PERIOD: late Ordovician Period (445-458 Million Years ago) Data: Lituites is an extinct nautiloid genus from the Middle Ordovician and type for the Lituitidae (a tarphycerid family) that in some more recent taxonomies has been classified with the orthocerids and listed under the order Lituitida. it's now considered widespread, Fossils have been found in New York, Argentina, Norway, Sweden, Estonia, and China. Lituites produced a shell with a planospirally coiled juvenile portion at the apex, reflective of its tarphycerid ancestry, followed by a long, -

Lingulichnus verticalis (Hakes, 1976). Humber RIver area, Toronto, Ontario, Canada. Late Ordovician, Georgian Bay formation, Lower Member. Oblong to tear shaped burrows made by linguliid brachiopod, species unknown. Approximately 15 cm across. -

Phycodes flabellus (Miller and Dyer, 1878). Georgian Bay formation, Lower Member. From the Humber River, Toronto, Ontario, Canada. Late Ordovician burrows organized in a flabellate pattern. Approximately 10 cm across and in width. -
A tergomya mollusc that can be easily found in the Humber Member of the Georgian Bay Formation in Toronto. This one is set on a limestone hash plate dominated mostly by pelycopods. On a personal experience I have come across more Cyrtolites specimens than gastropods at Mimico Creek. Reference: Ontario Department of Mines. The Stratigraphy And Paleontology Of Toronto And Vicinity.

Little ripple marks caused by the gentle currents on the shallow late Ordovician sea floor of Toronto. Georgian Bay formation, Humber member(?), Humber River area, Toronto, Ontario. Limestone slab, the coin is a quarter at the bottom for scale. Hmm, I'm beginning to decide if I should have taken this home with me today. Also at the bottom are two clam negative casts: a Whiteavesia and a Modiolopsis.© (©)

Ever since summer vacation started I have been free to explore the Humber River area and made frequent hunts there in the late Ordovician rocks of the Georgian Bay formation of the city of Toronto. I realized that I did not have a substantial amount of material from this location that I discovered by accident, and so I decided and started to invest some time in exploring this particular location. Last year I only made seven visits, but I did not hunt productively, as I was in my first year of fossil collecting and as a result I had very little material from this location. I knew this location

I found these two fossils from Mimico Creek in Toronto, Canada and they both belong to the Georgian Bay formation, late Ordovician. The first one I believe is a Pseudolingula, but I can't really nail it down to a species level. The other is a bryozoan, and I was thinking of Prasopora. What do you guys think? The brachiopod I found in shale, but the bryozoan in a limestone bed with other bryozoas. The brachiopod: The bryozoa:

I found the attached at a Quarry in Rockford. The area is supposed to be Late Ordovician, however I did find some Silurian fossils there, such as a Dawsonoceras. Anyway, I have yet to find anyone who'd been able to come to a conclusion on what this is. I believe it may be a coral polyp, but I just don't know. Help? The 'bulb' is 1.5CM wide The 'stem with top' is 1CM tall I appreciate your help! -Hannah
