KOI Posted June 15, 2019 Share Posted June 15, 2019 Hi! I recently acquired a bunch of microfossil samples for kids to play but did not expect them to be so small. We tried some microscopy but ended up applying a little trick that actually to helped to film them "in action", which was kind of cool. I do not know if this technique is a common knowledge or not but I decided to share. Perhaps, it will be of use to somebody. Here you go: Any suggestions for improvements? Thanks! 11 Link to comment Share on other sites More sharing options...

Brett Breakin' Rocks Posted June 15, 2019 Share Posted June 15, 2019 This was extremely informative and very well executed. Excelsior ! Cheers, Brett Link to comment Share on other sites More sharing options...
ynot Posted June 15, 2019 Share Posted June 15, 2019 Very nice video! Thanks for sharing this piece of work. Only suggestion is to use a needle or dental pick to manipulate the matrix. The tweezers are to big/blunt and make it harder to move just the things You want to move. 3 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

KOI Posted June 29, 2019 Author Share Posted June 29, 2019 Here is another video from travels in the world of microfossils and playing with a hybrid of a camcorder and a microscope. Who would have thought that those fish eggs are actually tube worms made of foraminifera? 2 Link to comment Share on other sites More sharing options...

Coco Posted September 26, 2019 Share Posted September 26, 2019 Hi, What is the fossil seen "2:50 mn" ? It looks like shark or ray dermal denticle. Sorry, I am french and I didn't understand comments on video. And a question that I have been asking myself for a long time and which I have never understood the answer : what are conodonts ? Parts of the jaws of worms or tiny animals ? Another part of an animal ?

KOI Posted October 9, 2019 Author Share Posted October 9, 2019 Hi Coco, if you mean the last video, it's a conodont element. They really can be quite different in appearance. Conodonts are so to speak "problematic" fossils. We still do not know what they were. Link to comment Share on other sites More sharing options...
doushantuo Posted October 9, 2019 Share Posted October 9, 2019 WHOA! Coco,les conodontes sont des elements (plus ou moins) dentiformes(alors,part de cavite buccal)des petits animaux plus ou moins vermiforme(ou peut etre un peu en forme des poissons juveniles),avec symmetire bilaterale,essentiellement Paleozoique (avec un moindre distribution dans le Triassique),et on pense qu'ils sont liees a des premiers vertebres. Particulierement dans le Devonien,ils ont un importance vraiment massive dans le biozonation/biostratigraphie (Me*d**,le derniere temps j ai fait un chose similaire... Enfin... Ils existent des vue differentes sur leur fonctionnement et systematique,and that's putting it mildly un example des recherches histoloques avec des vues prescients/precognizants,a l'aube des etudes geochimiques et histologues "moderne": quinethistosteo6932_38_bulle-30.pdf Guy-Elie Quinet: Contribution a l'etude de la structure histologique des conodontes lamelleux Bull.Inst.Roy de Sciences Naturelles,t XXXVIII,v.30/1962 below: image from:https://www.geochemicalperspectivesletters.org/documents/GPL1912_SI.pdf The "dental"/oral elements are shown in white 1 Link to comment Share on other sites More sharing options...
