Please help with ID of sponges, corals and bryozoans
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I collected some interesting specimens in Jurassic- Early Cenozoic erratics like sponges, bryozoans and hexacorals and also two primitive Ordovician sponges. The sponge pieces are 3-8 mm length (In yellowish limestone on sponge has very interesting skeleton growth outside). The size of coral in greenish gray limestone is 9 mm diameter, in the white limestone- 7 mm diameter. The bryozoans are from 7 mm to 1 cm length, they web shaped. Please help with ID of these fossils if you could. Best Regards Domas 1. Late Jurassic sponges in my opinion. 2. Early Cretaceous (?) sponges. 3. Late Cretaceous- Paleocene sponges I think.

As a graphic design artist I sometimes like to create some paleo-art and pop-art mash-ups. Please feel free to comment.

Hi, my name is Sérgio Jorge and I live in Goiania - Brazil. during a fishery I found in a pile of gravels which in my view is a vertebra( Cranial base?) and a fossilized seed. If anyone has an idea whatsoever, I would really be grateful! these are the coordinates of where I found the fossils! 18 ° 21'03.1 "S + 52 ° 01'36.4" W

I have an ammonite(?) that I received circa 1990 from a missionary who said that it was "brought down from the mountains by monks" in Papua New Guinea. Apparently, there is relatively little known about the palaeontology of the area. There are similar ammonites showing up in native tribal art pendants (see article in "Deposits Magazine" HERE The article indicates that it is not known whether these ammonites that are showing up are recently imported or of local origin. I suppose mine could have been imported, but given the date of acquisition and what I was told, I am inclined to think it was collected in situ in Papua New Guinea, but I can't be certain. The geologic map I found did not distinguish between periods in the Mesozoic, so I don't know if it is Cretaceous or Jurassic, etc. I did find 2 papers (Both available as .pdf online): Tatsuro, M & S.K. Skwarko. 1991. Ammonites of the Cretaceous Ieru Formation, western Papua New Guinea. J. Australian Geology & Geophysics 12(3): 245-262 Tatsuro, M & S.K. Skwarko. 1993. Cretaceous ammonites from south-central Papua New Guinea. J. Australian Geology & Geophysics 14(4): 411 - 433. The closest resemblance of the taxa in those papers was Subthurmannia (Fauriella) boissieri. In doing my own searching, I thought Macrocephalites bifurcatus (middle Jurassic) looked like a good match and has been collected in Papua (see link to museum specimen HERE). The preservation of that specimen appears to match mine, too. Here are some pics of my specimen. Any help from the ammonite enthusiasts would be greatly appreciated! @Ludwigia

Silicified specimen from Jurassic/Cretaceous/Paleogene marine sediments of Małopolska region, Poland. From secondary deposit, so precise age and locality unknown. Similar to a humerus, e.g. of a turtle. Or is just a sponge?

My most recent and most exciting acquisition, a giant partial vert from a tyrannosaurus rex from the hell creek formation of Montana. Nearly went into cardiac arrest that I was able obtain such a large specimen from t rex, so I thought I would share. It really fills up the dinosaur collection and feels like it weighs a ton, I think the dimensions are somewhere around 6.5 inchs or so long and 10.5 inchs tall if I remember, would've been alot taller if the process was still intact and I like how the giant pores are visible cause of the damage. Super massive piece, I was worried about it collapsing my shelve but it fits fine so far.

Hi all, I recently found this on a trip to the Jurassic Coast at Dorset and have been intrigued by this find, i'm not an expert on fossil identification and i would be grateful for all your potential ideas as to what this could be.

Hi! I found some pieces of mesozoic bones. I know that it is just pieces, but may be it is possible to ID some of it. I found it near Ili river in Kazakhstan. It belongs to cretaceous period for sure. Tyrannosauridae, Ankylosauridae, Titanosauridae, Triceratops Marsh and some other types were found here earlier. I use sm. scale. One more

While visiting family, my cousin showed me a fossil he collected at the coast when he was a child, cracking rocks to see what he could find. They spent a lot of time on the Jurassic coast, but also went to places like Hunstanton, which have Cretaceous layers. I'm really not sure what this is, but it's something in a flint nodule. Could it be a bryozoan?

I have finally found the courage to display just 3 of the fossils that I have...as I am just a "baby" in terms of even the novice hobbyists. I cannot guarantee that they are all completely clear of matrix material. I am concerned that my as of yet limited knowledge, could/would likely negatively affect the "Arrested Beauty" that has been set before us; as a "annal" before before written language. These fossils were found at home, in my backyard near Maple Valley in King County Washington. As I have said before, I am new at this, but as far as I can tell from the limited information I have found in my search for clues, the area where I live has formations from the Mesozoic, Jurassic and Cretaceous periods. My best educated guess (if you can call mine educated), is that at least number 1 and 2 (from left to right) are foot/hand bones from a Pterosaur. I am fairly confidant that #3 is one end of a femur. Unsure of the animal given that to me, they all look so very similar. I am absolutely not confident enough to make a guess as to the specific species. I am skeptical of my general assessment, given that I have found no evidence that any other fossils of the like have been found in the area; immediate or otherwise. I have also found what I believe to be small diameter pieces of fossilized ivory/tusk here. With that being said, please be gentle. I keep talking myself out of even posting these out of fear of making yet another fool of myself (only in a different way). I defer to my much much more experienced peers. Please do let me know if any other angles, etc. are needed for identification.

Mesozoic od Poland. Echinoid test? Eggshell? Reptile osteoderm? Coral, sponge, bryozoan?

Assortment of ray plates. The plate top right is one of the biggest plates I've ever found intact. -

Here's another view of the teeth with special attention to the larger fragment near the center. This piece is most likely a great white or other large predatory shark. I doubt it's a megalodon, but it could be or one of it's smaller cousins. I've found meg shards at the cliffs before. -
