Ancient Pelomedusoides

Just showing of some of my drawings I intent to use in an article I'm writing for the journal TRIONYX of the Dutch-Belgian Turtle Society.
The article shows the enormous variety in skull shape and size with the extinct relatives of the Pelomedusidae and Podocnemididae.







And the shell of Cordichelys antiqua.





Enjoy the pics....

Nice job !
Once the article is done could we please see or have it ?

Merci beaucoup!

The article will be in Dutch...I doubt you can read it, but a pdf will be available of it afterwards.

Some new artwork...


Cearachelys placidoi




...and Taphrosphys sulcatus.

Oh damn !
I can't read Dutch... too bad for me. It won't be available in English ?

Otherwise, congratz for your new artworks. Do you use some kind of "pattern" to make these draws ?

Oh and, you still did not check the sex of my Castaneus lol.

Has Ferry seen the light coulored belly one ? Perhaps that an animal from the dry/ savanah area.

Could you check it out please ?

Thanks for the sharing Ferry !

Most probably not...

All drawings are redrawn from other works of Gaffney et al., yet are done in such a way that lay-people can understand them better. The shell drawings are done in my own style, giving them a more natural appearance.
I work with Illustrator and Photoshop.

Oh yes I did...

A lighter coloured specimen yes, yet not looking like a true Senegal/Mauritania type.

Oh ok I see.

nice. Yeah I like the style of your drawing

Oh you checked my castaneus :o. So ? what do you think they are ? (male/female)

hmm.. so the light coloured one is from the dry savanah ?
What country do you think ?

Keep posting your drawing if you can ! That's interresting

Well, here you are....
To be included in my article: Pelusios niger.

Thanks.

Is that a P.Niger skull ?

Oui. Skulls of Pelomedusa subrufa and Pelusios castaneus will be used too, as does the skull of Podocnemis unifilis.

Hmm okay.

Why are some part colored with different colors ?

skwateur a écrit:Hmm okay.

Why are some part colored with different colors ?

To indicate the different bones that make up the skull.

Oh ok !

You should try Blender and make some 3D drawings :o

Here are the colourcodes for the bones making up the skull.

O_o
too many bones !

I have a question Ferry, I've read one of your post and you were talking about Pelomedusidae and Pelomedusoid, what's the difference ?

Pelomedusidae = Pelomedusa + Pelusios and
Pelomedusoid = pelomedusidae + Podocnemididae ?

Family Pelomedusidae = Pelusios + Pelomedusa
Hyperfamily Pelomedusoides = Araripemydidae + Pelomedusidae + Euraxemydidae + Brasilemys + Podocnemididae + Hamadachelys + Bothremydidae.

Hmm okay..

Most of the species you've mentionned are no longer present right ? (Araripemydidae, Euraxemydidae, Brasilemys, Hamadachelys and Bothremydidae)
Never ever heard of them :o

Right, they are indeed extinct families.
If you are really interested in turtles, you should take in mind that if you want to know the present, you should first know the past. In other words: extinct turtles.
Trust me, you have not even the slightest idea of the enormous variety and distribution of turtles in the past.

Let me show you 2 extinct turtles with quite an unusual appearance...


Sinemys gamera




Ninjemys owenii

I have a little idea of the enormous variety of turtle in the past.

Yet, I'm still a student and I do not have time to learn something else that my studies.

Anyways, where did you find these pictures ? :o
