GeschWhat posted a topic in Fossil IDI was going through a large group of very small Triassic coprolites today and came upon this. Since there was a beat up Koskinonodon tooth in with the coprolites, I'm wondering if this could be a jaw or maxillary fragment from a juvenile. The person who found the coprolites said that he found a lot of Koskinonodon teeth in the area as well some from Phytosaur, Apachesaurus, Coelophysis, Postosuchus, and Revueltosaurus. What do you all think? Jaw or maxillary? Amphibian, fish or something else? If this is amphibian, can anyone identify the bone above and to the left of the teeth? My cat votes amphibian @Carl check it out!
Was out looking for fossilized shark teeth today along a beach on the east side of Amelia Island in north Florida. Came across this instead. Don't know what it is. Conical in shape with a slight curve to it. Is it a fossilized tooth? From what? Any help appreciated. Cannot figure out what it came from. Thanks!
Hi, as a beginner this is a great resource to receive IDs on stuff I would never be able to figure out on my own. The first is a scale of some sort, about an inch long, half inch wide with a notched end, and an enameled middle rising to a slight point near the notched end. The second (have two very similar) is about an inch wide with points on either side, 0.3 inch long with a plate of six long teeth (?) on each side; the opposite side has two big depressions and the leading edge between the points has fine scales (or teeth?) The third (have three, one worn away to a nub) is wedge shaped with a blunt point in front(?), half inch long, less than an inch wide. The top(?) is roughly triangular with a medial crease, the sides flare up in the back. The bottom has a medial ridge, depressions on either side, and thickening to the sides and on either side of the front point. There are four holes/channels visible from the back, and these merge into one opening on the side. There is no enamel, looks like fine bone. The three samples were collected at three different places near the Rappahannock river. The last is the most difficult to describe. From the bottom it looks like a small pecan (an inch long) with one end more pointed than the other; there are hints of black bumps on the sides. The blunt end is flattened on top with small ridges on either side. Two enameled ridges arise together in the middle then join into a single notched ridge which continues to the point. It must be a piece of something else but I don't recognize anything else like it. My cell phone pictures are not great but I appreciate your ideas as to their IDs!
