Families missing

The page needs to be completed with a listing of superfamilies and the remiaing 9 families. Dysmorodrepanis 13:50, 6 February 2007 (UTC)

Origin

Protostegidae

The family's oldest member is Santanachelys gaffneyi,known from a specimen excavated from Brazil in 1998. The species first appeared during the Early Cretaceous.As an early sea turtle, Santanachelys had several unspecialized characteristics such as distinguishable digits in its flipper-like arms.

Cryptodira

Cryptodires evolved primarily through the Jurassic period, and by the end of the Jurassic had almost completely replaced Pleurodires in the lakes and rivers, while beginning to develop land-based species.

When is the origin of Cryptodira??? --H335 (talk) 02:58, 23 September 2008 (UTC)

"Cryptodira and Pleurodira: These subordinal names were based on the French vernacular names, Cryptodères and Pleurodères, originally used by Duméril and Bibron 1834. Cope (1864, 1865, 1868b) has generally been credited with authorship of these names, and he was the first to use the exact names Cryptodira in 1868 and Pleu-rodira in 1865, but previously used the name Pleurodera in 1864." http://www.iucn-tftsg.org/wp-content/uploads/file/Accounts/crm_5_000_checklist_v1_2008.pdf page 000.23.

Dysmorodrepanis's cryptic reference note

I'm moving Dysmorodrepanis's cryptic reference note here in case someone wants to find it and see if it is useful.

What are we wanting to do with this? Cheers, Faendalimas ^talk 14:58, 22 May 2012 (UTC)

Cryptodiramorpha

"The Cryptodira as understood here are called Cryptodiramorpha in this view." What does that mean? What is Cryptodiramorpha? Regards, SunCreator ^(talk) 10:01, 22 May 2012 (UTC)

Cryptodiramorpha is a name coined by M. S. Lee in 1995 it refers to all forms of the cryptodirous (hidden neck) turtles including some extinct forms not closely related to the modern cryptodires. The reference is (Lee, M. S Y. 1995. Historical burden in systematics and the interrelationships of ‘parareptiles.’. Biological Reviews 70:459–547.) It is available from a number of the journal sites that require login so I cant link it. I have it and am happy to email it if anyone wants it. Or you can make a login for yourself by searching online. It is an unnecessary name if you like as its pretty much synonymous with the term Cryptodira, at least for our purposes here.

190 Ma?

The turtle page says that their temporal range is 157 Ma. to present. This page says Cryptodira appeared 190 Ma. Am I missing something? Jonathan Tweet (talk)

Neck Retraction

Created a new section titled 'Neck Retraction' that focuses on the anatomy and morphology of Cryptodires. It focuses specifically on the cervical vertebrae; hopefully, more information will be added on the topic of neck musculature in the future. This information is from research and dissection being done at a university lab. Petrikyv (talk) 03:32, 5 May 2018 (UTC)
