Moroccan Parotodus parasymphyseal and Cretolamna biauriculata?
ThePhysicist posted a topic in Fossil ID
Hi y'all, I picked these shark teeth up from a local rock shop. The first is definitely a symphyseal/parasymphyseal tooth but I'm not sure if it's from an Eocene Parotodus or Otodus. I lean towards Parotodus because of the narrow crown and its significant curvature. The second I think is a Cretolamna biauriculata. The symphyseal is about an inch ~ 2 cm in length. @siteseer@Al Dente@MarcoSr@Untitled Parotodus sp.?: Cretolamna biauriculata?: -

Nothing extraordinary, but I found an area with several chunks of matrix with teeth in them. -

An incomplete tooth (just the crown) sitting in the red layer. Likely from Cretolamna. -

Any tips to differentiating Cretodus and Cretolamna teeth?
Jared C posted a topic in General Fossil Discussion
Hey ya'll - despite my best efforts I have a very tough time telling apart the teeth of Cretodus and Cretolamna - most of what I gather so far is that it *seems* that the blade on a cretodus is sometimes slightly longer and less robust compared to cretolamna, but this has large variation and might not even be a real pattern worth noting. Any tips? -

Below are five shark teeth I am trying to make sure I have identified correctly. Teeth 1-4 were found in North Myrtle Beach, though I do not know where tooth 5 is from. I believe that #2, #3, and #4 are C. Appendiculata, but am not confident in that. I wonder if #1 is as well, the shape seems a bit different in my opinion. Thanks!

Didn't find much this time. I don't think it's rained in a while - the water looked stagnant. Also was picked over well. Favorite find is the mostly complete Cretodus (found it under a fallen tree).-

Hello. I was wondering if I could get any more information on this tooth. I purchased it from our favorite auction site. The seller described the tooth as unknown genus/species and from the Cretaceous Coleraine Formation of Coleraine, Minnesota. I was unaware that Minnesota had Cretaceous sites? I almost didn’t believe the location provided. I looked up the Coleraine Formation and found that it was Late Cenomanian in age and located really close to Grand Rapids, Minnesota. Based on the age and morphology, I have IDed the tooth as Cretolamna appendiculata. Does anyone

There are two visible shark teeth (that I could see). -

I found less stuff than last time, but I found a nice centrum and a shard of a mosasaur tooth. A couple teeth grouped with Scapanorynchus may be Serratolamna sp. -

Cretolamna teeth from POC. The largest one seems to be the C. dwardius as described in Welton and Farish's guide, the others are C. appendiculata. -

There are four visible shark teeth in this one shot! Hint: three are right next to each other. -
Back again for more information. These teeth are driving me nuts. I am working on a Coniacian deposit from north central New Mexico, and have gotten around 20,000 fossils from sifting and screen washing ant hills. The vast majority are scapanorhynchids (over 12,000), but there are at least 25 other species represented. These teeth come from a possible barrier island deposit, and the wave action prior to fossilization must have been intense, since almost all the teeth are missing roots. There are around 1500 teeth that look like scapanorhyncus cf. raphiodon, but they have no

Hi everyone, I am seeking more information about the spectacular Cretolamna fossil featured in the respective wikipedia article. Aside from being a great fossil it has some interesting features, such as a large second dorsal fin. However, there doesn't seem to be anything else online about this specimen. Does anyone know anything about this - is it in a private collection? Can it actually be referred to Cretolamna?

Hello all, I purchased two small Moroccan shark teeth and would like to nail down their species. I think they are either Cretolamna appendiculata or small Otodus obliquus teeth. Please let me know what you think.

I am currently researching Cretalamna for a written article. When searching for images, I came across this peculiar one that I find interesting. No information on this image seems to exist, whoever submitted this photo did not add any sort of description, other than the shark was identified as "Cretolamna sp." However, I feel too curious to not scrutinize this photo. In my attempt to scrutinize the details of this photo, I've concluded a few things. Firstly, it is likely that the fossil came from Lebanon, possibly Cenomanian lagerstattes in Hgula or similar localities,

Hi everyone, I found a Cretolamna tooth that has subtle secondary cusplets in the Cretaceous streams of Monmouth county NJ. I was wondering if this is variation within appendiculata or suggestive of biauriculata maroccana. Any thoughts would be appreciated as always. I hope to take some better pictures soon. The tooth in question is on the left with a typical Cretolamna appendiculata on the right for comparison.

This tooth was found on my most recent trip to Purse State Park. I believe it is a Mackerel Shark tooth, Cretolamna. I think this may be my first truly pathological tooth because it does appear to be deformed. The crown of this genus does not typically slant to one side so much as this one does. Also, the crown is twisted rather than flat, much like the crowns of Physogaleus contortus. The thing that most leads me to believe it is pathological, however, is one of the cusps. The first cusp seems normal, but the other is twisted at a 90 degree angle and seems pressed against the crown. Can I get

Help needed to identify these shark teeth. Responses are appreciated. Thx.
