  1. About 5 years ago I had a paper published in a few newsletters and a Forum member asked if it was published in it's entirety because it seemed incomplete. Well, I reviewed the issue of the DVPS newsletter and, sure enough, the entire "Results" section was left out. For anyone who cares, here it is in all its glory. https://docs.google.com/document/d/1XWuV6BvSU8tAfmQUDEzZmLiZNijx8JWNo6UOUiBSI1c/edit Tom
  2. borings(?) & potential ostracod:)

    hey all! i was going through some of my stuff & found this pretty cool rock- it’s from anticosti island and has many ichnofossils in the top & bottom- i’m thinking they’re borings. on the bottom i noticed a figure vaguely resembling a circle- from what i can tell, it’s an ostracod. opinions & feedback are very much appreciated, & thank you in advance!!
  3. Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone formation, Texas 1 small vial of Cretaceous Lower Gault Clay, East Wear bay, Folkestone, Kent, UK A micropalaeontology slide with Jurassic Blue Lias matrix rich in holothurian material. A thin section of an Ostracods filled Elimia snail from the Green River Formation in Wyoming A thin section from the Rhynie chert of Scotland which should contain preserved parts of the plant Aglaophyton major and perhaps even other species. I also got a lot of Bull Canyon micro fossil teeth and 2 cretaceous mammal teeth from Hell Creek In this topic you will be able to follow my path through this newly discovered hobby as I will post my finds and progress Currently I am only working with a clip-on cellphone microscope, but I do plan on getting a professional microscope in the next few months! (Tips are always welcome) So let's put on our Ant-Man suit and explore the microfossil realm So here are some of the first pictures I made of some of the microfossils Starting with the thin slices! Thin slice with Ostracon filled Elimia tenara snail from the Green River Formation, Wyoming Thin slice with Aglaophyton major from Rhynie Chert in Scotland
  4. Ostracod or something else?

    Hi, I have another mysterious fossil. Silurian. Ostracod? Any ideas? (Bottom right): Side View:
  5. Ostracod? Ontario, Ordovician

    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
  6. I realize this is modern, but I thought it was unique enough to share. While ostracods are pretty common in this matrix, this is the first time I've seen one like this. It's not my area of expertise, but this one looks conjoined.
  7. Hollinella pumila

    Identification based on page 63 of "Ostracods of the Middle Devonian Silica Formation" by Kesling and Chilman (1978). This was a float sample
  8. Kirkbyella bellipuncta

    Identification based page 54 of "Ostracods of the Middle Devonian Silica Formation" by Kesling and Chilman (1978)
  9. Arcyzona homalosagenota

    Identified based on key table on page 70 of "Ostracods of the Middle Devonian Silica Formation" by Kesling and Chilman (1978).
  10. Ostracod?

    Hi. I found this in Lancashire, UK in the Pennine Lower Coal Measures formation. Is it an Ostracod? I find a lot of Ostracods in shale but I've never seen any Ostracods in British Coal Measures sandstone. It measures around 5mm long. Thanks, Daniel
  11. I have about 8 acres of coastal estuary in northern Nova Scotia, and decided to take a look at the estuary sediments to see if I could find any fossils. Yes, they are there! Microfossils and lots of other life including ostracoda. Using my hand lens I could see them very well. Will invest at sometime in a microscope and maybe I will see even more. Hand lens for scale for foraminifera and ostracod scale is in millimeters.

  14. Ostracods.

    So I have found a couple more ostracod pieces. Sadly small pieces and very fragile.... The loupes I ordered came in the mail so tried to snap a couple shots, starting with my original pieces (have positive and negative). This isn't a great pic and hoping to get better ones tomorrow. It is through a 5x loupe. Will add future ostracod pics to this post!
