pleecan Posted January 21, 2011 Share Posted January 21, 2011 (edited) Discovered Jan 20, 2011. Middle Devonian Era Arkona / Hungry Hollow ON Hamilton Group Ultrasonic treated Ostracod and resulting fracture / cleavage to reveal a rare glimpse of preserved internals micro-organs? It has been graceously pointed out to me that the internal organs could be just debris caught in the carapace.....

pleecan Posted January 21, 2011 Share Posted January 21, 2011 Neat find Peter! Do you have a photo of the other side of that carapace? Hi Dan: Thanks Dan.... Just one halve so far ... there are hundreds/ thousands of tiny bits to scan through... odds of finding the other half is kind of slim.... more like a random walk ... all my micro fossils are the waste products of silt collected at the bottom of an ultrasonic cleaner that would have been thrown out but now I save and analyse the contents under magnification.

Peter Oh, sorry Peter, I guess I wasn't very clear! Do you have a photo of the other side (external surface) of the specimen? Did you flip it over and photograph the outside?

pleecan Posted January 21, 2011 Share Posted January 21, 2011 (edited) Okay Dan: I found the Ostracod and retook shoots front and back and using a much sharper optic configuration ... Imaged using a point and shoot Nikon 995 with a 4x plan microscope objective... photographed at 3 megapixel then cropped.....

pleecan Posted January 21, 2011 Share Posted January 21, 2011 Thanks Mike and John. I find direct coupling a 4x flat field plan microscope objective matches perfectly to the Nikon , Nikkor lens with very sharp resolution... and excellent depth of field.

Acryzona Posted January 21, 2011 Share Posted January 21, 2011 Peter, Nice photos. Ostracods look different in water than when photographing them dry. If you are entering it in IPFOTM, you may need a name. I think it is a Poderodictya punctulifera. Good luck!

You also have a super entry with the micro jaw... what a great find! Looks like the microfossil entries are making a strong prescence.

dhk Posted January 22, 2011 Share Posted January 22, 2011 (edited) Seeing as it was sunny and about 30 degrees on January 11, 2011 and as we were expecting 2 feet of snow the next day, I decided to get myself out to the Mt. Tom site and try to dig another dino track out, last chance for the year type of thing, well after three hours of chipping away, I did get one out to add to the shelf. The rest, will have to wait till the spring thaw. So since the chances of me finding anything to enter in the FOTM in January in New England are slim to none, I just had to enter this dino track. Dinosaur footprint fossil-Grallator ( "stilt walker")(210 myo) Made by a dinosaur very much like a Coelophysis, this track was made by a small to medium- sized bipedal carnivorous theropod dinosaur. The stride of their walkways show that they were probably the fastest dinosaurs in the Connecticut River Valley of Massachusetts. They may have attained speeds of up to 20 miles per hour. The dinosaur that left this track probably reached a length of 3-7 feet. The track is almost 7 inches from middle toe claw to heal. The grid in 1/2 inch. So this is my second FOTM entry, a rear winter find from Massachusetts. Edited January 23, 2011 by dhk Link to comment Share on other sites More sharing options...

Acryzona Posted January 24, 2011 Share Posted January 24, 2011 Hi Larsa, If you have a camera with threads on the end of the lens, then you can purchase a microscope eyepiece that can be screwed directly onto the camera. It's a lot cheaper than buying a microscope with a phototube. I have a Nikon 4500 with a threaded eyepiece. I don't remember where I purchased the eyepiece but if you are interested, send me a PM and I'll dig through my notes.

pleecan Posted January 24, 2011 Share Posted January 24, 2011 Larsa: Acryzona is right... I also have the Nikon 4500, 995, 990 all have the adapter that can be found on ebay and works great... and plugs directly into the microscope oculars... Perhaps a more cost effective solution is... You can also buy a USB eyepiece and take pictures directly through the ocular of your microscope.... that way you don't have to buy the camera.... http://shop.ebay.ca/i.html?_nkw=usb+microscope+eyepiece&_sacat=0&_odkw=nikon+995+adapter&_osacat=0&_trksid=p3286.c0.m270.l1313 PL Link to comment Share on other sites More sharing options...
imakeitrain Posted January 24, 2011 Share Posted January 24, 2011 My IPFOTM entry is a Middle Devonian scolecodont (annelid worm jaw) from the Silica Formation at Fossil Park in Sylvania OH. I found it this morning (15 Jan) and identified it as Leodicites sp. The total length of the jaw is 0.5mm (~0.02").
