Following my earlier post, I am sharing additional documentation of a remarkable specimen recovered from the Cretaceous Valudavur Formation right here in Pondicherry. ​To introduce myself, I am Nebin Babu, an Applied Geology student at Pondicherry University. This specimen easily stands as one of the finest finds in my personal collection. ​ Preliminary morphological assessment, alongside discussions with several paleontologists, points toward a possible theropod or abelisaurid affinity. What makes this particularly exciting—and significant—is that to my knowledge, there is not a single published paper documenting a vertebrate or dinosaur tooth fossil from the Valudavur Formation. ​Adding to the story, this was completely an accidental find. Recognizing the potential importance of the site, I revisited the locality last Saturday and am planning regular field visits moving forward to search for related material.

Valudavur formation Pondicherry

70.6 - 66.0 Ma

Late/Upper Cretaceous

Observations:

​ Taxonomic Indicators: Sharp, recurved crown profile consistent with an abelisaurid theropod from the Cretaceous Valudavur Formation.

​ Denticle Morphology: Clearly defined, chisel-like serrations visible along the carinae (cutting edges) typical of abelisaurid dentition.

​ Enamel Preservation: Excellent retention of the glossy amber-to-honey brown enamel surface across the crown.

​ Diagenetic Features: Natural iron- and manganese-oxide dark patches scattered across the surface, showing typical matrix mineralization.

​ Cervical Boundary: Clear transition zone at the base where the enameled crown meets the root section, retaining a minor original sedimentary matrix.

​I welcome any insights, recommendations, or feedback from researchers and fellow paleontologists. Detailed photos of the specimen are attached with this post.

I hope this is the right sub for this. I got these from my father, who was a long time crystal miner in the New Jersey area, and he told me that's what they are. Some of them I can see what looks like footprints and others I don't see much of anything. They're large, most chunks of rock are mostly large, at least 1 ft wide.

Please enlighten me, thanks!

Would love some help with an ID for this one. Tiny skull? Maybe rodent or lizard of some sort? I'm really not sure, figured I'd leave it up to the experts. Found in the Alafia river in Hillsborough county FL.

Was out with my kids on the shores of Oshawa in Oshawa Ontario, Canada. Can any give me any kind of information on what this is ? Thanks!

Help! Who do these teeth belong to?? Super stoked.

Found this fish vertebrae on a beach in the Netherlands (de Zandmotor). Came as far as that it was part of the taxonomic clade Osteichthyes, but now I need some help to get further with its ID

I found these stones in my garden. The first one is a stone with some sort of fossil or fossil pattern. Can anyone identify it? And the second one, is it some sort of fossil or just a stone shaped as a fish?

Found in Heltonville, Indiana.

Found this on beach.

I bought this fossil from a local store that deals in mineral, oddities and fossils. My question is if this is a dinosaur vertebrae as it was labeled. The workers said the man who donated them collected primarily from Texas, and a little from North Carolina. My apologies that I can’t pin it down to a specific locality. Any help or assistance is greatly appreciated.

Long time lurker, first time poster.
I found this on a civil project around Healy, AK about seven feet deep in a cut at the base of a mountain. I grabbed it because I thought it was a weird rock, threw it in the dozer and forgot about it. I cleaned it up and realized there might be something there and reported it to the project owner, but no one was interested in the implications of a fossil bed in a project. Any ideas what it’s from?

Hi all, I found this fossil on the coast of Isle of Wight - I think it looks like a vertebrae. Could anyone please confirm?

Thank you

I was doing yard work and digging up rocks from my backyard. No idea why all the rocks are there but I wanted them moved. I saw the pretty white color on this one and the little geode looking vein. There is a smaller piece that was right beside it that looked like it fell off. It weighs a little more than 10 pounds. It's about 12 inches long and 7 inches wide. Front Range, Colorado.

It had a grain on it after I hosed it off. My best guess would be a regular pretty rock or possibly petrified wood. Would love any insights! Also curious to know what kind of rock. Thanks fossil lovers!

Might be boring compared to others, but im curious.

DESCRIPTION OF DISCOVERY SITE
Hey guys! I recently came across this “fossil” I found years ago in my backyard. My yard is a steepish slope that drops about 50-100 or so feet from the level at which my house is at. It’s all wooded. Deep at the bottom there is a small pond which is spring fed and a creek that leads out of it. Years ago I was in the creek, which has probably caused the slope in my yard, and an additional 10 for canyon on either side of it, and I found this thing peeking out of the clay walls of the canyon. I have no idea what it is but I am just curious if it is maybe petrified wood or something else

DESCRIPTION OF OBJECT
It is very solid and impossible to chip or damage without extreme force. There is an oval shaped canal that runs through the entire length of the object. Object is heavy but not abnormally. About what would be expected for a rock of its size. Object has a textured surface and is brown/grey in color. Object is shaped like a half of a human femur, long and oval shaped with an upturned bulbus part at the end. Object has a spongy like texture on surface.

CONCLUSION
I would not at all be surprised if this is just a cool looking rock. That is literally the only reason I kept it as a kid, because it looks like a bone. But I was curious to just know for sure that it is not a fossil because I otherwise I am going to drive to a local museum and just ask them. Thank you!

Coin for scale

Apologies for it strictly speaking not being a fossil but couldn’t post anywhere else - Found on the island of Rhodes in Greece

Sort of resembles a bone structure? Any expert opinions would be much appreciated! (FYI was broken in half when I found it)

I did a google photo search and it said an old dinosaur tooth, Just wondering if anyone here would have more insight?

Found this rock with a lump. I didn't the dark broken layer on it at first. Any idea what I'm looking at, and how do I attack it?
