Random posting on Geology and Paleontology with a bit of spunk and sass thrown in.
Hmm...a very strangely weathered/deformed orthoconic nautiloid like Endoceras? Total wild guess there.
Hmmm....maybe. There is another thing from that area that I think is a nautiloid. Would/Could a nautiloid have that sort of "S"-ish shape to it though?
Is this a riddle where you know answer? Well, either way, my guess is it looks like it's related to a trilobite from my first glance. Is it a nautiloid? Looked like an arthropod to me.
I seriously do not know. That is why I am looking for help. Keep the ideas coming please!
It looks trilobitish to me. But I can see where one might think it's a cephalopod. Trilobite was my first instinct - a body fossil though, not a trace fossil like Cruziana. My guess is that the most clear 'end' of it is the tail of a large trilobite, and that the head is missing. The s-shaped bits could be leg parts or gills?
That is exactly what I though on first look Penny - trilobite. John did not think so :/
I was going to say trilobite body fossil as well but others beat me to it; so I will go out on a limb and say early vertebrate ("fish"), as it is segmented. Looks like a dorsal view with backbone extending posteriorly.
How old is it, first of all? Y'know, if this is a "new" organism, than I'll be a T-rex.
"Trilobite" was my first thought too, but I managed to convince myself that there were too many segments. I tend to think of trilobites having ~20 thoracic segments or less but I suppose there are some exceptions. Nautiloid sutures can be a little wavy but I'll admit the geometry doesn't seem quite right which was why I invoked deformation/weathering. Not feeling very confident about that though.
A friend of mine asked his invert prof. (one that works int he Paleozoic) what it might be and he thinks it is a nautiloid cephalopod irregularly sectioned, similar to Gonioceras occidentale.
My guess: Cruziana trilobite feeding path.http://www.trilobites.info/triloichno.jpghttp://english.fossiel.net/system/glossarium/trilobietspoor.jpghttp://www.edu.xunta.es/contidos/sec/bioloxia/biosfera/alumno/4ESO/terra_cambia/imaxes/cruziana.jpg
That is what I thought too Travis. But the more people we show it too the more we hear Gonioceras.Glad to have you back int he blogging world. How is the thesis coming? Have a defense date yet?
Is It That Scorpian I Heard About?Other wise it looks like a fish
