Mioplosus_Lover24 Posted June 20, 2022 Share Posted June 20, 2022 I was wondering if anyone ever made the claim to have the smallest articulated fossil, because I think I've got a decent shot! These are the smallest fish I've found so far. There are two Mioplosus labracoides and one Priscacara sp. 7 "Life is too complex for me to wrap my mind around, that's why I have fossils and not pets!"

jpc Posted June 20, 2022 Share Posted June 20, 2022 Interesting question, but the world may never know, as many folks here have no idea how big a US quarter is. Lots of international participants. How many mm are these little guys? As a guy who has collected the Green River quite a bit, those are nice finds. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted June 20, 2022 Share Posted June 20, 2022 I wouldn't claim that this is the smallest ammonite ever, but it is the tiniest which I've ever found with a diameter of 9mm. Cymaceras (Trochiskioceras) bidentosum, the microconch to C.guembeli. 1 Greetings from the Lake of Constance.

RJB Posted June 20, 2022 Share Posted June 20, 2022 I would think that someone would post some forams on this post. But I also have some very small fish. Even made a video of them. Going to post it youtube one of these weeks. RB 1 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 20, 2022 Share Posted June 20, 2022 Trilobites can be very small, as well as ostracods, forams, and all other types of fossils. I think you would need to specify a group of fossils to get a good answer. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Paleorunner Posted June 20, 2022 Share Posted June 20, 2022 (edited) To give an example in trilos, this is the smallest I have. Eoredlichia sp. (0.3 centimeters). Lower Cambrian. Yunnan China. Well no, I'm wrong, I have a secret Santa gift from @Misha a small Itagnostus of 0.2 centimeters . From Wheeler Shale - Utah.

Lower Cambrian. Yunnan China. Based on finger size of about 20 mm wide, you must mean that the trilobite measures about 3 mm. My goal is to leave no stone or fossil unturned.

Mark Kmiecik Posted June 21, 2022 Share Posted June 21, 2022 (edited) Does a bacterium count? About 3 microns average. Edited June 21, 2022 by Mark Kmiecik 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

If its fossilised, I'm sure the world is your oyster! You could definitely find some teeny stuff in amber / copal, The smallest articulated molluscs and brachiopods I've found have diameters of less than 2mm, they are usually around 1-3mm. ~ Isaac; www.isaactfm.com "Don't move!

Sylvestersen Posted March 2, 2023 Share Posted March 2, 2023 I know this is a late replay to the original question, but I might be the one who have tried clamed the title. In 2013 I tried to get the Guinness World Records title for 'smallest fossil vertebrate/ fish' with a Moclay Balistes SL=4.8 mm from the Eocene (Ypresian) Fur Formation. but I got this reply from Guinness World Records "Thank you for sending us the details of your recent record attempt for 'smallest fossil vertebrate/ fish'. We are afraid to say that we are unable to accept this as a Guinness World Records title. While we do not underestimate your achievement, we have heard of fossils being smaller than the one you mention in your application. Experts have discovered fossils measuring tenths of a millimetre." On one point i agree, there are smaller fossils out there but I stil believe that this is one of smallest fossil of a fish or anything with a vertebra for that sake ever to have been found. The scalebar on the photo is in millimeter 3 Link to comment Share on other sites More sharing options...
rocket Posted March 2, 2023 Share Posted March 2, 2023 (edited) 4.8 mm, thats tiny Edited March 2, 2023 by rocket 1 Link to comment Share on other sites More sharing options...
jpc Posted March 2, 2023 Share Posted March 2, 2023 and the folks at Guiness obviously don't know the difference between vertebrate and invert fossils. Great little fish... and nice photo of it. 4 Link to comment Share on other sites More sharing options...
JBkansas Posted March 2, 2023 Share Posted March 2, 2023 I have some 1-2 mm agnostid trilobites from Utah. I'll see if I can get a picture tonight. 1 Link to comment Share on other sites More sharing options...
