JimB88 Posted September 24, 2010 Share Posted September 24, 2010 Not too many people pay much attention to one of the earliest forms of multi-cellular life on this planet - unless its time to wash the car! So lets give em' some love.. I'll start with an example from the Ordovician - Dystactospongia... I had originally thought this was a bryo, but after examining it with a loupe I realized it was a sponge. Link to comment Share on other sites More sharing options...

glacialerratic Posted September 28, 2010 Share Posted September 28, 2010 (edited) Don't know the ID on this one. I picked it up this past spring out of a pile of quarry rock that will eventually become rip-rap along the shore of Betsie Lake, a natural harbor on Lake MI. The rock is Devonian.

kreidefossil Posted October 26, 2010 Share Posted October 26, 2010 Hey, after a long time another post by me: The Sponge (maybe Chonella or Seliscothon) was found in 2004. Age: Upper Cenomanian Sediments nearby Dresden (Saxony, Germany) - part of the Bohemian Cretaceous Basin (BCB) www.kreidefossilien.de - The Cretaceous of Saxony (Germany) Link to comment Share on other sites More sharing options...
Wrangellian Posted November 10, 2010 Share Posted November 10, 2010 I'm not sure if these are sponges - one guy told me he was skeptical, that they were just plants, but they sure look like the crosshatched structure of a Hexactinellid to me! And the plant material from this site all has at least a thin film of carbon (coal) in it, while these have none. If they are sponges, they are the first examples I know of from the Cretaceous of Vancouver Island. Maybe I'll post this in the ID section too.. If anybody has a strong opinion one way or the other I'd appreciate hearing it. I have others I can put up when I get pics of them. Link to comment Share on other sites More sharing options...

I picked it up this past spring out of a pile of quarry rock that will eventually become rip-rap along the shore of Betsie Lake, a natural harbor on Lake MI. The rock is Devonian. Nice specimen, Looks like you have a brachiopod, sponge and maybe a bryozoan all in one! (I'm pretty sure there is a type of sponge with 6-rayed spicules, tho I can't name it offhand).

Wrangellian Posted November 10, 2010 Share Posted November 10, 2010 cambrian sponges from utah. first 3 pics Chanceloria pentactica 4th pic unsure. Brock NICE! Did you find these yourself? (Care to trade one of those for a few Cretaceous ammonites or something? ) The 4th pic looks to me like Chancelloria too. NOTE: According to 'The Fossils of the Burgess Shale', Chancelloria is not a sponge, but a 'scleritome-bearing animal' (extinct group). So it qualifies as a Cambrian oddball.. that's even cooler than a sponge if you ask me. Eric Link to comment Share on other sites More sharing options...

Wrangellian Posted November 29, 2010 Share Posted November 29, 2010 Here's a Diagoniella sp. from the Marjum Fmtn, Millard Co, Utah, or so I was told. When I received it I was a little disappointed that there was no appreciable detail visible on it than what I could see in the pic, but I was reassured that it is what it was stated to be. It's got the right silhouette, at least! (Does anyone know if this can be pinned down to a more specific location than 'Millard Co.'?) Link to comment Share on other sites More sharing options...
MikeR Posted December 1, 2010 Share Posted December 1, 2010 Here is something that you don't see every day: Cenozoic sponges and two different species on the same matrix piece. On the left Rigadrella trabecula Rigby, 1881 and on the right Ophiraphidites infundibuliformis Schrammenn, 1899 from the Comfort Member of the Castle Hayne Formation, Middle Eocene, New Hanover County, North Carolina.

piranha Posted December 1, 2010 Share Posted December 1, 2010 Here is something that you don't see every day: Cenozoic sponges and two different species on the same matrix piece. On the left Rigadrella trabecula Rigby, 1881 and on the right Ophiraphidites infundibuliformis Schrammenn, 1899 from the Comfort Member of the Castle Hayne Formation, Middle Eocene, New Hanover County, North Carolina. Great fossil! I'm confused however with regard to the attribution of Rigadrella. The treatise volume of Porifera does not list it as a valid genus. The closest I found in name is Rigbyella and these are described from the Cambrian of Iran and Texas. Ophiraphidites is described in the literature from Cretaceous deposits exclusively which leads to a different conclusion on this fossil. Prof. Rigby would be the first to admit to being an oldtimer these days but he was in his heyday in 1981 not 1881 - that's the most obvious problem with the attribution. Can you shed any light on how your fossil was evaluated? The structure appears tabulate - is it possible this is a coral? Link to comment Share on other sites More sharing options...

Wrangellian Posted December 2, 2010 Share Posted December 2, 2010 Over at http://inyo.110mb.com/dv/poletaarch.htm I have two images of branching archeocyathids (they look kinda like miniature examples of a Saguaro cactus in the rocks...), Class Irregularia, I collected several years ago from the Lower Cambrian Poleta Formation, California. Archeocyathids are an extinct variety of calcareous sponge. Interesting pieces Inyo. There's something to put on my 'got to get' list - Archeocyathids. Are they particularly hard to get? I don't live in an Archeo. area. Link to comment Share on other sites More sharing options...
