I don't know where exactly the Mixosauridae belongs on the ichthyosaur family tree, but even I know it shouldn't appear three times in different locations on said family tree. Someone with a little more knowledge on ichthyosaurs should fix that at some point. 75.209.106.105 (talk) 18:04, 31 March 2008 (UTC)[reply]

re "Ichythyosaur" stubby article merger, as well as being a mis-spelling it contains incorrect information (ichthyosaurs were reptiles, not mammals). But I'll incorporate the more factual information of that stub. M Alan Kazlev 00:17, 13 May 2005 (UTC)[reply]

Popular Culture

Why is the reference to They Might be Giants in popular culture being repeatedly removed? —Preceding unsigned comment added by 71.237.161.42 (talk) 04:58, 6 April 2008 (UTC)[reply]

If it weren't for the "Nine Bowls of Soup" song, I'd have never landed on this wiki and learned so much about the Ichthyosaur. Soon kids everywhere will be singing his praises. —Preceding unsigned comment added by 164.223.72.5 (talk) 02:51, 2 July 2008 (UTC)[reply]

So, if you found this page because of the song, why does the song need to be mentioned, since anybody who find this via the song will obviously already know about it? In other words, mentioning the song will not teach you anything more about Ichthyosaurus, other than the fact it was in the song, which you already knew ;) Does the song itself teach you anything about Ichthyosaurus? Or try to? If so, then it could be mentioned. For now, if anything, Ichthyosaurus could be mentioned on the page about the song, if there is one, in case people listening to the song want to look up the animal but don't know how to spell it, etc. Dinoguy2 (talk) 07:24, 2 July 2008 (UTC)[reply]

I would consider it relevant as a resource for early education. I loved dinosaurs as a kid. 99.16.209.16 (talk) 03:08, 5 March 2013 (UTC)[reply]

Skeleton reconstruction and tail-fin

According to my references, the reconstruction of the skeleton from 1863 is wrong. There was a large dorsal fine, but it did not have a bony support and, therefore, was at one time not known to have existed and so it is not shown in the old reconstructions. There was a large asymmetrical tail-fin, in the vertical plane, which was stiffened by a downward bend of the vertebral column (a reversed heterocercal-type fin stiffened by the posterior caudal vertebrae). --Dysmachus 13:15, 5 March 2006 (UTC) cf. Source[reply]

...and the "broken" tail has been miscorrected, according to a Stephen Jay Gould article. This illustration would be a good base for a history subsection, though. --Wetman 23:15, 5 March 2006 (UTC)[reply]

The flippers

In the early ichthyosaurs, all their limbs seems to be of similar size. But in some of the later species, the hind flippers appears to be much smaller than the front flippers. Could this reduction of the reduced hindlimbs be a beginning trend among these reptiles? In that case, maybe they would have disappeared completley with time if they hadn't become extinct.

It's possible, and it seems to have happened in whales, which evolved pretty convergantly with ichthyosaurs. But we'll never know for sure.Dinoguy2 00:13, 6 May 2006 (UTC)[reply]

Order or suborder?

The Ichthyopterygia article says that group is a superorder and Ichthyosauria is an order, but here it says Ichthyopterygia is an order and Ichthyosauria is a suborder. The Paleobiology Database[1], which is edited by university professors, favors the former, but I'm still not sure. What should it be? Jerkov 21:24, 15 June 2006 (UTC)[reply]

Have a look at Handbook of Paleoherpetology, Part 8: Ichthyopterygia This is a serious and up to date scientific monograph. In the classification they give, Ichthyopterygia is a superorder and Ichthyosauria is an order. I suggest we use this work as our reference for ichthyosaur classification. M Alan Kazlev 22:41, 15 June 2006 (UTC)[reply]

Agree, I'll standardise to this if I come across anything that needs to be.Dinoguy2 23:42, 15 June 2006 (UTC)[reply]

What does it say about what subclass? The Ichthyopterygia article says subclass Diapsida, but this article saus subclass Euyapsida. Things should be harmonized, but which way? Bytor 00:09, 22 March 2007 (UTC)[reply]

Phrasing

Scientists who believe in the Evolution theory suggest that the ichthyosaurs lived during a large part of the Mesozoic... This was in the introduction, I dont think it is appropriate for the article based on scientific evidence. Enlil Ninlil 02:03, 14 January 2007 (UTC)[reply]

No, it certainly is not appropriate. Good catch, his seems to have been a fairly recent addition that was missed. Dinoguy2 04:38, 14 January 2007 (UTC)[reply]

Behavior/Intelligence?

What were their brain/body ratios? What areas of the brain were largest/the most interesting? I'm guessing the optical lobes were proportionately large, but it would be nice to see what scientists currently think about what these animals thought. Were they rather dim like lizards, or was their demanding, competitive environment pushing them into producing bigger brains over the millions of years they developed? What do we know?

Eye rings

Any idea what purpose the bony eye rings served? Other creatures seem to get along fine without them. -- Writtenonsand (talk) 13:17, 16 January 2008 (UTC)[reply]

Sclerotic rings are actually present in a lot of things, like dinosaurs and birds, but not crocs and mammals. I don't think there's an accepted answer yet for their function beyond generally supporting the eye, but I imagine that would useful for an ichthyosaur, living underwater with gigantic eyes. J. Spencer (talk) 14:21, 16 January 2008 (UTC)[reply]

So where did the DOLPHIN's dorsal fins come from?

This isnt so much a request for information as just a comment that evolving a dorsal fin might not be that big a deal considering that the cetaceans did it sometime around the reign of Basilosaurus, also presumably from nothing. (Some whales seem to lack dorsal fins, but they could have evolved and then disappeared.) —Soap— 14:32, 20 March 2011 (UTC)[reply]

'Reproduction' reference

Does the editor or can someone else verify the source for the first paragraph describing viviparous reproduction? It sounds plausible, but there is no reference cited.
