I was recently sent some Wheeler Shale material from the Antelope Springs area of Utah, Middle Cambrian age. Thanks to my good friend Debra @Paleome It's all rather splendid stuff, not the usual Elrathia kingii or Itagnostus interstrictus, but a selection of wonderful more unusual things. But what about this one? A trace fossil of a burrow? Some sort of sponge or algae? Any help will be greatly appreciated, as always. Thank you. The inside of the object is an orange brown colour, while the outside and surrounding regions are sort of beige. It reminds me of some

Why is the difference between fossils and trace fossils important?
Daniel Fischer posted a topic in Questions & Answers
First of all I want to make it clear that I know what are trace fossils an I know the difference between fossils and trace fossils, but I feel like I am missing something. In a few posts here on the forum I saw people saying things like "this is not a fossil, maybe a trace fossil" and things like this and I do understand that regular fossils give more information but can anyone please explain to me why it seems like trace fossils are worthless compared to regular fossils? -

.These fossils are from Romania. They look like crustaceans ichnofossils. If these Eocene or Oligocene fossils are really traces of crustaceans then what genus did make them? If you think that you can identify them write your opinion here. Thank you very much.

From my previous trip to Ellsworth County, Kansas and it's located in Dakota formation, Cenomanian. It appeared as almost like vertebrae but I'm sure it's not verts. Is it by chance some form of ichnofossil? @jpc thinks it's concretionary. No disrespect to him, he's the only one who offered his opinion and I would like to know if anyone else have a different opinion.

I found these that resembles burrow or root cast in Ellsworth county, Kansas, USA from my previous trip. The formation these came from are most likely Kiowa formation/Kiowa Shale and the age is Albian. Here's the link to my previous trip. I'm just catching up with the prepping and sorting my fossils from my previous trips. I am wondering if it is some sort of ichnofossils. Is it burrow, root cast, or something else? Also, is it possible for it to be from geological origin rather than a true ichnofossil? This one is the largest I found. The center is poorly cemented sandstone and can

Oviposition-Scars On A Calamite Stem From The Westphalian D Of The Piesberg, Germany
paleoflor posted a topic in Member Collections
Dear all, It was difficult, very difficult to wait with posting, since I am very, very excited about this fossil find. However, I also wanted the Dutch magazine version to come out first. Well, it finally did this Tuesday, so here is some info in English, along with a couple of the figures. During a visit to the Piesberg near Osnabrück (Germany) in 2010, I found a stem fragment of Calamites decorated with strange, elongate-oval structures [Fig. 1]. While those features were unusual and quite remarkable, it proved difficult to find information about them and the fossil consequently went into- 25 replies

Looking for ID help. I originally thought the fossils were triticites because I found some chert with definite triticites at the same location. But the fossils in the pictured rock are indeed elliptical shaped from the top view (like triticites), but are circular from the side view. The rock is limestone from Pocahontas County, Iowa. The third through sixth photos are microscopic (~40x). The last photo shows a coral located on the underside of the same rock. Fusinilid? corpoloite? ichnofossil? Or what? Your ID info will be appreciated.
