GavySwan Posted September 9, 2018 Share Posted September 9, 2018 Hi all, Found these itty bitties in a park in Orillia, Ontario. They’re not in situ as they’re in ornamental stones around the playground. We also find lots of gastropods and brahiopods in these stones. Not having rocks in situ is less than ideal but “urban fossil hunting” is awesome when you’ve got young kids in tow! I’ve never actually seen ostracod fossils before, so just wondering if these could be some? They look like the approximate right shape. They are quite tiny, around 3-4 mm. Canadian quarter for scale. Thanks for any help! Gavy Link to comment Share on other sites More sharing options...
Innocentx Posted September 9, 2018 Share Posted September 9, 2018 They're the right shape but larger (ones here are about 1 mm) than what I find in Kansas. I don't know if they attained this larger size in your area, but quite possibly. 1 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Pumpkinhead Posted September 9, 2018 Share Posted September 9, 2018 That's within the reasonable size range for ostracods. I saw ostracods that were about that size very frequently in the Gull River formation for work this summer and they are also fairly ubiquitous in other Ontarian paleozoic rocks. 3 Link to comment Share on other sites More sharing options...
Peat Burns Posted September 9, 2018 Share Posted September 9, 2018 And sometimes they get really big! I found these in the Silurian of Mich a couple weeks ago. They are 2 *cm* in length. 2 1 Link to comment Share on other sites More sharing options...
GavySwan Posted September 10, 2018 Author Share Posted September 10, 2018 Thanks so much, folks! They’re pretty cute lil’ dudes, at any rate. I’ll hit the books and see if I can find anything more about them in this area, specifically. Gavy Link to comment Share on other sites More sharing options...
Johannes Posted September 10, 2018 Share Posted September 10, 2018 Maybe Eoschmidtella, or her relatives? (No° 4 on the plate: Ordovic_Ostrac ) Other genera possibly fitting here might be Hemeaschmidtella , Pseudoancora or Vogdesella. The smooth-shelled genera are allways very tricky...

Northern Sharks Posted September 10, 2018 Share Posted September 10, 2018 They are pretty common in the Gull River fm. rocks in the Orillia area and the size is right. Eoleperditia do get bigger, but there are juveniles. Most ostracods in the area are smaller than yours. There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
