7 years, 1 month ago7 years, 1 month agoHello, @vperez, @zacharias-allison
Here is a link to the page Victor is referring to. It has most of the common teeth you can find at Aurora. This should help you I.D. almost all of your shark finds from Aurora.

7 years, 2 months ago7 years, 2 months agoHello,
I don’t think it’s a tooth. The coquina layer in the Pungo River formation at Aurora is cemented together by limestone full of those tiny phosphate grains that I see in your sample.
It looks like a piece of coquina matrix from the Pungo River that just happens to have a tooth shape.
Later!

7 years, 2 months ago7 years, 2 months agoHey Lisa,
PennDOT blew up most of the marine zone while widening the cut a while back. There are occasionally chunks of marine zone that have fallen that people can search, but chunks of the plant layer are much more common to find.
I was there about a month ago to make sure the site was not blown up…again. I only spent about 15 or so min…[Read more]

7 years, 2 months ago7 years, 2 months agoI’m still going to say it’s a Bryozoan colony encrusting the bottom part of your spiriferid fossils.

Jayson Kowinsky replied to the topic What is this brach on top of? in the forum What Is It? 7 years, 2 months ago
7 years, 2 months ago7 years, 2 months agoNo clue! It looks tiny. I would go with Eleanors suggestion as a poorly preserved piece of Brachiopod. Gastropods are usually smoother, I’d go with Brachiopod, but same idea.

Jayson Kowinsky replied to the topic Brach on coral? in the forum What Is It? 7 years, 2 months ago
7 years, 2 months ago7 years, 2 months agoHello,
This is a cluster of poorly preserved spiriferid brachiopods. They are found in clusters on occasion.
As to what type (genus) they are, I have no clue. There are lots of types and these ones are too worn to see any of the genus specific traits.
I attached a picture tracing them out on your image, and also an image of a similar cl…[Read more]

Jayson Kowinsky replied to the topic Ordovician in the forum What Is It? 7 years, 2 months ago
7 years, 2 months ago7 years, 2 months ago@hunter-thurmond – No, the Needmore formation is not equivalent to the Mahantango. However, they are very similar.
They USED to be part of the same group. Now, the Mahantango is part of the Hamilton group, while the Needmore shale is part of the Onondaga Group.
Looking at the stratigraphy, the Magantango is on the top, the Marcellus shale is i…[Read more]

7 years, 2 months ago7 years, 2 months agoHey, I just saw that a member of the Needmore formation in West Virginia and Pennsylvania is the direct equivalent of the Onondaga Limestone in NY. I wonder if your fossil came from that, or a layer just above or below the limestone?
About your size. The one I attached as the picture is the biggest one I’ve found. Most of them are very sm…[Read more]

Jayson Kowinsky replied to the topic Is this a fossilized bone? in the forum What Is It? 7 years, 2 months ago
7 years, 2 months ago7 years, 2 months agoI agree with @rnarducci . That chunk is similar to some stuff that you can find in Virginia. I don’t see any bone in it. Lots of shells, and that big eroded thing in the middle with the radial striations looks like coral to me. In Virginia, bone chunks and shark teeth can be found in that hard “greensand” rock, so I would say keep looking!

7 years, 2 months ago7 years, 2 months agoHello,
Ya, it’s the very top of a solitary coral. I have seen lots of those in the Needmore formation in Virginia. Although it’s a different formation and time period, I’m sure they can be found in other formations. I attached a picture from the “Lost River” site on my webpage. This one, the very tip was visible like yours, and I extr…[Read more]
