Sinopaleus Posted June 16, 2011 Share Posted June 16, 2011 alright, so i got myself a new fossil. it's a huge horn coral the size of a banana, and it's got a really rough texture. it's from Guangxi Province, and the seller claims that it is from the Ordovician. can someone please I.D this coral for me? thanks!

Carl Posted June 16, 2011 Share Posted June 16, 2011 It's almost certainly a horn coral but it shows pretty clear signs of being tooled - the "segments" have been... let's say enhanced. Link to comment Share on other sites More sharing options...
Xiphactinus Posted June 16, 2011 Share Posted June 16, 2011 It kind of looks like they glued 2 horn corals end to end to make one twice as long as normal. Note the line through the middle. Those Moroccans are creative folk! Link to comment Share on other sites More sharing options...

Dromiopsis Posted June 16, 2011 Share Posted June 16, 2011 (edited) Hello, It's true that in the first picture, we can think about a montage but with the others pictures(2&3), we can see the calice. Perhaps it's a characteristic of this specie. Agitated environment, changing of T°C, or competition with others corals(Light, space...) can influence the growth and shape too. I am not enough specialist of rugosae coral from ordovician period to give a name of genus.

Regards D lol, im glad to hear that. i saw another horn coral identical to this one, both huge in size, but that one didn't have any broken segments. i hope that helps Link to comment Share on other sites More sharing options...
Shamalama Posted June 17, 2011 Share Posted June 17, 2011 I've seen those corals for sale on E-bay and thought about getting one but was always leery because they looked doctored. I could see most had been in an acid bath to clean them which often removed any associated epifauna that might have been there. Yours looks like it has been on a grinder to make the regular segments and the very base looks shaped as well. They are cool looking but I want as natural looking as possible! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Sinopaleus Posted June 18, 2011 Author Share Posted June 18, 2011 for picture 3, the strange dent you see is possibly caused by a rock. the dent is somewhat round, but the other sides are perfectly fine. in the segments below are exposed agate. the agate seems to have replaced the inside of the coral loong before this was discovered. geez... that reminds me of the red agatized horn corals from utah! but the agate in this is clear.

hrguy54 Posted January 11, 2012 Share Posted January 11, 2012 It doesn't look fake to me. I collect in Ohio, much smaller ones.Largest is 4-5 inches. I've seen them this size and larger from upstate NY. I was given one, in fact, that is about 5 inches but if "straightened out" could be 6-7 inches.

JohnJ Posted January 11, 2012 Share Posted January 11, 2012 Henry, I think the last photo clearly shows grinding on the upper half of this coral. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

I would suppose that horn corals can get pretty large, but the coral in the link you provided has two very straight lines on it... On the other hand, the ribbing looks much more natural than on the upper part on Henry's example. At least Henry got his for free. And now the horn coral dance...

araucaria1959 Posted January 12, 2012 Share Posted January 12, 2012 Rugous corals of that size (and even larger) are no rarity in the middle devonian reefs of the Eifel region (Germany), e.g. Meerbüsch locality near Ahütte (Givetian). Size alone is no argument that two individuals must have been glued. araucaria1959 Link to comment Share on other sites More sharing options...
dudeman Posted January 12, 2012 Share Posted January 12, 2012 (edited) If you take a look at the thread entitled "how many horn corals are there?" I posted my largest @ just over 8 inches. It not only very large, but has great detail. I would post a link, but I am on a plane right now. Maybe somebody can give me a hand? EDIT: Here you go: >LINK< to other pictures.

howard_l Posted January 12, 2012 Share Posted January 12, 2012 I have gotten one of those also, I thought they were Ordovician but I found a very nice web page called Paleozoic corals that has discribed it as Devonian, They have put a genus name of Kuechouphullum from the Guangxi Province , China.

Sinopaleus Posted January 12, 2012 Author Share Posted January 12, 2012 that's reasonable it is said to be from guangxi province saw a few more for sale inside the country. to me, its obviously not glued together lol massive specimens have indeed been found inside guangxi province, near the place where the brachs (spirifers, atrypas etc) were found Link to comment Share on other sites More sharing options...
howard_l Posted January 12, 2012 Share Posted January 12, 2012 The Devonian is known for it's large Rugose coral, The ones from China are small Compared to the Devonian Rugose from louisville at the Falls of the Ohio.

hrguy54 Posted January 12, 2012 Share Posted January 12, 2012 I'm holding in my hand a 6-7" horn coral very similar to these pictured. They have similar lines'striations as those some of you think are grinding marks. Mine is authentic - from upstate NY. No doubt these pictures are valid. Excellent specimen as far as I'm concerned.

Pierre Posted August 13, 2017 Share Posted August 13, 2017 Hi guys, I have a question. I attached the foto of the fossil. What it could be? Fossil horn? Link to comment Share on other sites More sharing options...

This is an orthocone cephalopod. Not a horn coral. It would help You to start Your own thread rather than hijack someone elses thread. Also if You include a scale and location information.
