chrisrobertson Posted September 19, 2010 Share Posted September 19, 2010 I found this thing while I was hiking. What is it. Link to comment Share on other sites More sharing options...
Scylla Posted September 19, 2010 Share Posted September 19, 2010 It is a rock. There are areas that look like sutures but tho overall shape doesn't look like any skull I've seen. More in focus pics of the ends may help and some info about where its from will help with the age. Link to comment Share on other sites More sharing options...
Auspex Posted September 19, 2010 Share Posted September 19, 2010 I wish I could look at that in the hand; the aforementioned "sutures" are real interesting, and I can just make out some other interesting things on the better lit part of the end in the 4th picture. Can you post a sharper pic of that area?

tracer Posted September 19, 2010 Share Posted September 19, 2010 looks like a well-worn piece of a cretaceous ammonite to me... Link to comment Share on other sites More sharing options...
Scylla Posted September 19, 2010 Share Posted September 19, 2010 looks like a well-worn piece of a cretaceous ammonite to me... thought of that but the "sutures" are oriented the wrong way OR it was a huge ammonite and only a small portion survived... That repeating pattern on the thicker end may be a fossil, can't tell from the pic. Link to comment Share on other sites More sharing options...

JohnJ Posted September 19, 2010 Share Posted September 19, 2010 Chris, you might try setting your find on a non-moving surface to photograph it. The combination of camera hand shake and holding your find tends to blur fine details. Also, you might switch the camera mode to macro (usually indicated by a tulip icon). The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Scylla Posted September 19, 2010 Share Posted September 19, 2010 OK thanks for the new pics. I think it is just a rock with a cool shape sorry. Link to comment Share on other sites More sharing options...
chrisrobertson Posted September 19, 2010 Author Share Posted September 19, 2010 Really? Even with the fissures running down the side??? They run all the way through it. Link to comment Share on other sites More sharing options...
MikeD Posted September 19, 2010 Share Posted September 19, 2010 Redo the 2nd pic at the top of the posts. Those sure look like ammonite sutures. The other angles do look like just a rock. Link to comment Share on other sites More sharing options...

Auspex Posted September 19, 2010 Share Posted September 19, 2010 And the only camera I have is with my droid phone cam. For a phone cam, that's pretty good!

tracer Posted September 19, 2010 Share Posted September 19, 2010 ok, i retract my always hasty assessmentnocitatiousness of its potentiometric possibilinessitude. i now think it's a rock doing a bad imitation of a sutured and therefore interesting cretaceous Thingamajig sp.

Auspex Posted September 19, 2010 Share Posted September 19, 2010 I messed with the 4th pic a little; here are the patterns that caught my eye: Are they there, or is it an artifact of the lighting?

chrisrobertson Posted September 19, 2010 Author Share Posted September 19, 2010 I thought it kinda favored this a little. Link to comment Share on other sites More sharing options...
Auspex Posted September 19, 2010 Share Posted September 19, 2010 I think the resemblance is superficial; there is no sign of bone structure in the broken end of your item, and the "suture" line would still be unexplained.

flyguy784 Posted September 19, 2010 Share Posted September 19, 2010 Don't believe they're sutures. Please correct me if I'm wrong here. The purpose of a suture is exactly that, to suture, to tie together the two ajacent segments. If you look at the angles and interaction between the two sides, there is no suturing.

Mr. Edonihce Posted September 19, 2010 Share Posted September 19, 2010 ^^^^ Using a word to define or not-define itself may be confusing to others. I think I know what you mean though.....I was looking at it, thinking that, even though the first thing that came to my mind was Ammonite sutures, I'm not sure if it looks 'organized' enough. Usually, Ammonite sutures seem to have some kind of predictable pattern ....eventually, once it goes far enough, you can see it either repeat or at least it will start to look like each separate jagged line somehow 'works together' as part of something that has purpose (accidentally through evolution, of course, but a found-purpose, nonetheless). This thing though....it just looks kinda random. I guess one more question would be... is there more than one 'line' of this suture feature, parallel with this one, or is this the only one on this piece (not that just one would be problematic)? If there is another parallel 'suture' line, does it somewhat follow along with this one in a closely mirrored pattern, or is it completely different? . ____________________ scale in avatar is millimeters ____________________ Come visit Sandi, the 'Fossil Journey Cruiser' ____________________ WIPS (the Western Interior Paleontological Society - http://www.westernpaleo.org) ____________________ "Being genetically cursed with an almost inhuman sense of curiosity and wonder, I'm hard-wired to investigate even the most unlikely, uninteresting (to others anyway) and irrelevant details; often asking hypothetical questions from many angles in an attempt to understand something more thoroughly." -- Mr. Edonihce Link to comment Share on other sites More sharing options...
