Large shark verts

[Joeymcd]

Is there anyone else on here who collects large shark vertebra? I am mainly interested in the ones from the USA. Although I have a bunch of ones from Morocco and all of them, or at least, most of them are over 4 inches.

Great collection.

And I love the square rocks with preserved plants in the background, too.

The pineapple is my favourite, beautifully preserved.

Is there any way to determine species or even genus on these vertebrae from Morocco.

Not that I know of.

Of course larger ones will belong to larger species but otherwise.

The verts from Morocco are from Otodus obliquus. Most of the large darker colored verts are from Otodus angustidens  from the Cooper and Wando river in Charleston, South Carolina.

I am not saying you are wrong but i am just trying to understand better. With the ones from morrocco what makes you say Otodus and not other species of shark that are present.

It is often assumed that these larger vertebrae are from Otodus obliquus due to the size, but I don't think it is a certainty.

I don't know about the USA species, but your capitalization is out. Species names are never capitalized. so this should be Otodus angustidens.

And, of course, Cooper and Wando.

[Joeymcd]

Yes, forgive me for the capitalization. I know that’s a very upsetting thing to some people. But I am voice texting all of this, and for example, I say the word Angustidens many times during the day because I am on many fossil sites on Facebook, and we talk about them all the time, so it naturally fills it in for me. The Moroccan verts are normally always found with teeth of the Otodus obliquus so that’s how we know that it came from that shark. In fact, the second picture is of an associated set of verts and teeth from one shark. The people that I buy from there are experts in the field so we all know what we are doing since we’ve been doing this for many many years.

Not upsetting at all, and I quite understand the voice texting problem, though a bit of self-editing might be beneficial.

Anyway, I correct these things for the benefit of other readers and will continue to do so.

I will have to take your word on Facebook being a great place for fossil ID.

"normally always" ? One or the other, old chap.

OK exactly who are you?? I don’t know how this works because I just joined recently and I’m trying to make a few post which no one is replying to whatsoever except you policing my every word! Are you an admin? Do you do this to everyone’s post and is  this normal? Would somebody else please enlighten me to who this person is and Why I am being ridiculed on every sentence I make here? If it’s going to be like this, I would just as soon not be in this formum at all.

This is a member who was just raising some points on your punctuation/grammar. 

As a science based forum, we do try to get things right, and instruct those who may not know any better.   We also try to make allowances for those who use speech to text, and mobile phones to type. (typos, etc.)  He wasn't ridiculing you at all, but was trying to point out/correct your errors.

 

We have no way of knowing that you know the scientific nomenclature rules.

 

Your lack of responses could be for many reasons. People aren't always on the Forum.  Or, ...for example, ... I did not respond, as I have little interest in shark verts, specifically. 

Sometimes, conversations take some time to gather momentum.

 

We are not like Reddit or Facebook, or other online communities here. We try to give people the benefit of the doubt. 

There are people from many different countries here, and not everyone's first language is English. Some tone or meaning may get lost in translation.

Please exercise some patience with our members.

 

Also, since you are new, and not familiar, there are settings under your account settings that allow you to ignore members.

If you are annoyed by corrective suggestions, you are free to ignore those who may upset you.

Thank you.

Welcome to the forum!  I didn't respond to your post because I don't have any verts anywhere near that size.  For a very specific type of collection, it may take several days to get responses, especially during the holidays.

I am very sorry to have offended you.

I am Adam and just an ordinary chap and member, very happy to meet you.

I apologise for the clumsy posts that I made which were in no way meant to ridicule you, just meant to inform others reading the thread.

I do this often, in no way was I picking on you.

Please forgive my clumsiness.

Life-s Good!

Adam

You have an impressive collection of very large vertebrae and really nice Otodus obliquus teeth.  I have always assumed that those large vertebrae from Morocco are indeed from the shark Otodus obliquus because I'm unaware of any other Moroccan described Moroccan shark species that could have vertebrae that large (Edit: possibly Palaeorhincodon) and the features of those vertebrae match those of the Otodus lineage.

 

I've collected thousands of shark and ray vertebrae (mostly very small, under one inch) from the Eocene of Virginia, US.  I've donated a good number of them for study, as not a lot is written about fossil shark and ray vertebrae, describing their features.  See some of the donated vertebrae in the below pictures.  Unfortunately, the study isn't progressing much at all.  Otodus obliquus is found in the Eocene Virginia fauna, but is not very common.  I've only found, based upon vertebra features, a couple of small Otodus obliquus vertebrae.
