svcgoat Posted August 2 Share Posted August 2 Pipefish Monterey Formation I found and collected this specimen myself and its unusually small. Is it complete? Is it a juvenile? 11 Link to post Share on other sites
connorp Posted August 2 Share Posted August 2 Can't help, but very neat piece. Congrats. 1 1 Link to post Share on other sites
Fossildude19 Posted August 2 Share Posted August 2 Definitely something from the Syngnathidae. Not sure if it is Syngnathus or Hippocampus sp. It looks to me like the caudal fin (tail) is missing, and maybe the dorsal fin? Mostly complete. It does look like a juvenile specimen to me. Great fossil, by the way. Excellent find! @rocket @oilshale 3 1 Link to post Share on other sites
rocket Posted August 2 Share Posted August 2 (edited) very nice and cool find! This is Syngnathus avus (Jordan & Gilbert, 1919), rare but known from the Monterey-Formation of California Congrets to this great fossil! e.g. I add the paper, the original one is figured on plate 29, fig. 2, and described on page 35 the pic in the book is bad, but there are some nice ones in the net to compare Fossil fishes of southern California (archive.org) Jordan_Gilbert_Montereyfishes.pdf Edited August 2 by rocket 5 Link to post Share on other sites
svcgoat Posted August 2 Author Share Posted August 2 @rocket I actually have a few larger specimens but I've never seen one this small. Is this even more uncommon? Link to post Share on other sites

I really do not know , my personal opinion is that it is a mixture. Smaller ones are harder to see, so they come up more rarely. But, might be they are...

Fossildude19 Posted August 2 Share Posted August 2 I would say juveniles are a bit more rare than adult specimens. Would love to see your other examples. 1 Link to post Share on other sites

svcgoat Posted August 2 Author Share Posted August 2 I have another one but when I coated it with paleobond the entire rock turned green. So I haven't coated the rest of them Link to post Share on other sites
rocket Posted August 2 Share Posted August 2 really nice finds, I go to unpack my Estwing and come Link to post Share on other sites
Tidgy's Dad Posted August 2 Share Posted August 2 Very nice indeed. Link to post Share on other sites
svcgoat Posted August 2 Author Share Posted August 2 Any idea why the entire piece turns green when I add the glue? @rocket @Fossildude19 Link to post Share on other sites
Fossildude19 Posted August 2 Share Posted August 2 I tend not to treat my fossils with anything, unless I absolutely have to. I find that Art Fixative is usually enough if something is really powdery or crumbly. I have no experience with any other consolidants, so unfortunately, I have no idea what happened in your case. Maybe one of the other preppers will know? @Ptychodus04 @jpc @RJB ?? 1 Link to post Share on other sites

Adding some glue or lasure is tricky, could do everything better or destroy... Edited August 2 by rocket Link to post Share on other sites
svcgoat Posted August 2 Author Share Posted August 2 I mean the fossil is still fine its just green I havent stabilized any of the others though because I prefer them to look as natural as possible Link to post Share on other sites
oilshale Posted August 2 Share Posted August 2 (edited) Was it really Paleobond? Which grade was it? Is it a milky white liquid? Some waterproof wood glues contain chromium salts as hardeners - these can lead to green discoloration Edited August 2 by oilshale 1 Link to post Share on other sites
svcgoat Posted August 2 Author Share Posted August 2 Yes paleobond I accidentally used the 750 adhesive Link to post Share on other sites
Ptychodus04 Posted August 2 Share Posted August 2 Did you use the accelerant to speed the drying of the Paleobond? This will react with clays in a matrix to turn the specimen green. Give the green part a little bath of bleach water. This will usually remove the green tint. I only consolidate with Paraloid B72 or Butvar B76 on dry specimens. It’s indefinitely stable and removable with acetone (if needed). 3 1 Link to post Share on other sites

RJB Posted August 3 Share Posted August 3 The accelerant will turn certain rock green. I've never had a problem with just the super glue itself, only with accelerant and only with certain rock. RB 1 Link to post Share on other sites
