    Flint sea sponge cap remains?

    I collected these off the Thames foreshore. I have been lead to believe that these are the remains of sea sponge (that they once held them, or were them??) but I don't really understand. Can someone here help confirm and explain this please? Thank you

    Interesting stones or maybe fossils?

    I’m really new to fossil identification but my nearly eight year old grandson’s recent passion has sparked my interest and we have been going through some of my beach stone pick ups I’ve always picked up interesting looking (or interesting feeling)stones and what I thought were shells- turns out I have quite a few fossils. The flint photos below were found on Whitstable Beach in Kent England. I joked and called them witches fingers but now I’m wondering… are there crinoids on the surface or just marks. The second stone I can remember one of the grandkids giving to me as it looked li

    Any Porifera People Out There?

    I pulled this out of the Mahantango Formation of Pennsylvania a couple weeks ago. It's middle Devonain. TI though as I pulled it out of the scree that it was more of the myriad corals, but looking at it more closely it is most certainly not (although there are a couple Rugosa tucked in there), the structure is all wrong. I was told by one sponge enthusiast that it is definitely sponge. some kind of sponge. I'm a taxonomist at heart, and it drives me nuts if I can't at least narrow something down to a family. The literature on porifera is woefully scant, especially on this coast. Looking a

    From the album: Westphalian cretaceous fossils

    One of my mostly loved sponges, Becksia soekelandi. Fragile, thin, hard to prepare. But..., always very cool. Comes from the lower Campanian of Coesfeld, same locality the Coeloptychium comes from. Height around 8 cm

    Coeloptychium sulciferum

    From the album: Westphalian cretaceous fossils

    In the "middle west" near Coesfeld lower and upper Campanian sediments occurs. Its possible to find everything..., including fantastic sponges. Some look like funges, called Coeloptychium. Perfect one, about 8 cm diameter and including stem and root

    A Few Micros

    From the album: Delaware Fossils

    A few of the hundreds of microfossils I found in one day of lying on the sandy spoils with a pair of reading glasses Coin is about 2 cm.

    Petrified Flame Sponge?

    Have you ever heard of Petrified Flame Sponge from Wyoming? I just bought (in the mail) the below piece because I want to look at it under a microscope and I think I can take some interesting pictures of it. It is supposed to be from the White River Formation in Wyoming. See the below cards with it. Marine from the White River Formation doesn’t make sense to me. Fluvial would, but not for sponges. Tsunami in Wyoming also doesn’t make sense. Reworked from older Formation? Ideas on what this is? Just a name for a type of agate? Petrified Flame Sponge Slab, Late Eocene/Early

    Sponge or Bone ?

    Hello! its my first time writing in this forum. i am from Germany and usuals discuss my findings in a German forum. But this time no one was able to identify my new fossil. it was found at the cost of the Baltic Sea in northern Germany. (You can expect fossils from every age, because of the ice age) You can see a sponge like structure with some big channels. It seems that the sponge like structure was once covered from some kind of “skin” as you can see in the pictures. the fossil measures 10“ x 4,7“ (25cm x 11cm) and seems to be heavy as a normal

    Sponge ?

    This was found on a gravel bar in the Trinity River in Arlington, Texas. From the color I'm guessing it is Cretaceous in age, but I've been told that the river tends to import rocks from a great distance, and Paleozoic fossils do show up. It sure looks like a sponge to me.
  17. Hi All, so I had heard about fossilized coral located in the Western Arizona desert near the Colorado River. So we went out there and did some rock prospecting ourselves. The location is La Paz, County south of Parker, Arizona. Namely, the terminal moraine-like hills about 10 miles south-east of Parker, Arizona beyond the Colorado River Indian Reservation. We found a ton of very interesting sponge or coral-like rocks on top of these hills. So this is consistent with a few other reports online about this. First, let me describe this location as it’s somewhat fascinating if you p

    Sponge or Coral

    I am supposed to identify whether this is a sponge or a coral but google is not helpful and neither is my professor. My instinct is to say colonial coral, but i would just like to be sure. Any insight would be greatly appreciated!
  19. Hi All, any thoughts on these specimens? Location is Roberts Mesa in Gila County, Arizona. (east of Payson) The red coral-like stems were found loosely on the ground very near the red trunk and gray matrix pieces. So I’m making some assumptions that the two are related as they were found maybe within 100 meters of one another. And the red stems above looked similar to the red trunks below of course. My first thoughts are some sort of coral but could they be a sponge instead? I’m assuming all are Naco Formation? Comments welcome. Photo size reference is in inches.

    Coral or sponge?

    Hi guys! I was in the Warsaw Geological Museum and there I came across this specimen which reminded me of Tabulate coral, but it was signed as a "sponge"... The sponge from the "maastrichtian age", when Tabulata already was extinct. I couldn't be more confused. This one still looks like coral to me. What do you think?

    Could you help identify please?

    Found in Muskogee, Ok near the Arkansas river. I originally thought this was just a piece of rhyolite the pink popping through the light gray caught my eye. Thinking its a rock we cut it ooen. Thats when I noticed some patterns and vivid colors and decided to remove the matrix which was pretty fragile. This is what I have uncovered so far. I am thinking this is a type of sponge either a Solenopora or a Stromatoporoidea. And thank you for any help.
  22. Hi there I'm just new to the Fossil Forum. I found this large fossil near the Abitibi River in Ontario. Thinking a sea sponge or Coral. It's large - 1.5 ft x 1 ft w x 8 inches in depth. Wondering if anyone could help with the ID or age. Thanks DB

    Can anyone ID this?

    My 13 year old son found this at the beach in Destin, FL. It reminds me of a tooth, but it's not pointed. Any ideas of what this is?
