Bryozoans And Corals. Age? Genus? Formation?

Recommended Posts

KansasFossilHunter

On a camping trip near Sedan Kansas (southeastern Ks) I came across thsese fossils. I know nothing about the age or formation they come from, although I would guess somewhere around the cambrian-Ordovician. Most look like horn corals, except for one that looks like a bryozoan. The Bryozoan is rather big, it fills the entire rock, coming out on every side...

Also, in a completely different location about 3 miles away, I found a spot where there are literally hundereds of crinoids eroding from the hillside. Some sections are half an inch in diameter and 3 in long!

Is anyone fimiliar with this kind of fossils and if so what is.... the Geological age? The Genus of the fossils? and (if posssible) the Formation? Any help would be appreciated, as these kind of fossils are way outside my realm of experience..

Thanks in advance!

By the KGS map, it is Pennsylvanian. It looks like the city sits on the border of the Shawnee and Douglas groups.

If the bryozoan you are questioning is the 1st picture on the bottom row, I think it is coral.

Nice finds!

Thanks! There was ALOT of sandstone in the area, with only impressions. The site was about 10mi NW of the city.

Isn't a bryozoan a type of coral?

Sedan, Kansas is known for fossiliferous exposures of Beil Limestone, which is within the Pennsylvanian Virgilian Stage. Most impressive are large slabs covered with Caninia horn corals.

There should be a whole suite of strata in the area, but your coral specimens indicate that you most likely hit the Beil.

I saw some huge plates that were too big for me to collect about 4 ft in diameter. Although I have seen some bigger ones in various fossil shows.
