As things are usually quite serious around here, I thought we might have a fun poll.

If you had the power to restore one of these extinct marine invertebrates to the modern oceans, which would you choose?

Boy...thats a toss up between the giant nautilus (ussesss?) and the sea scorpion...
But remember, when the elder ones (or is it the old ones?) come back, all that stuff comes with them too!
Yaaaay.

We know what all those animals looked like alive, except ammonites, so just a glimpse of a live one would be wonderful. To put them in the oceans today would give Steve & Kat way too much to do. And I would have to move closer to the sea and take up scuba. But what would I do with my poor old jackass Maybell? :(

I agree with Kevin, ammonites, but for a far more frivolous reason - their fossils structure is so pleasing and pretty, I'd like to see one in motion. No matter how many trilobite cookies I eat, I'm just not as excited about trilobites. But I'll post a photo of a trilobite fossil that was given to me soon.

Well, I would normally go for ammonites or belemnites but I think Hallucenogenia is just tooo weird & I'd loove to see one in the flesh (so to speak!)

No-one chosen the trilobite yet? Those things were not as popular as I thought!

Good choice Jean!

Here's a picture of a fossil and a recent reconstruction of Hallucigenia from the Cambrian Chen-jiang fauna of China. This animal is so weird it was named after a hallucination! Originally reconstructed as marching along the sea-bed with seven pairs of spines forming the 'legs'; it is now thought the animal was reconstructed upside-down. The animal probably walked along on tube feet with the spines running along its' torso projecting upwards. The 'head' is always indistinct and shows no clearly defined sense organs. The animal was probably related to the velvet worm, Peripatus, as part of the Onychophora and examples covered in armoured plates have been discovered in China.

Very strange indeed.

Well, we are over halfway and it's neck and neck, or rather mantle and thorax between the enigmatic molluscs and the armoured arthropods.

Could this specimen of Mixopterus swing the vote in favour of the bugs, I wonder?

What about Opabinia? Weird, weird, weird.

Phil
Oct 04, '03, 4:06pm
Opabinia?

Another cracking choice!

This Cambrian oddity had five eyes and a flexible trunk with a grasping claw at the end. It had a segmented carapace and has caused many a headache amongst palaeontologists keen on reconstructing and classifying this animal. Dr Sam Gon III has recently redescribed the animal and has interpreted the claw as being reconstructed at 90 degrees to its original plane. Opabinia, has also been reinterpreted as an anomalocarid so perhaps you could have voted for 6)!

The example below comes from the Burgess Shale. Dr Gon's images, with fantastic fossil specimens is available to view here:

Nipponites mirabilis was certainly one of the weirdest ammonites as can be seen from the link and the picture. It demonstrates possibly the most extreme derivation from the classic spiral shell shape amongst all of the ammonoidea, even amongst the heteromorphs. It looks like an irregular tangle of whorls but is really just an interconnecting mass of U-bends

It was a very late ammonite, it lived in the late Cretaceous and has been found in Hokkaido, Japan, and in North America implying it had a very widespread distribution. It has been speculated that this ammonite lived in the surface waters drifting at a shallow depth and feeding on plankton. The ‘head’ was probably angled downwards as it seized small animals with its arms. Given the shape of the shell it must have been a poor swimmer and probably had a lifestyle similar to a jellyfish. The animal must have rolled as it grew and probably had a changing orientation as it developed.

Good choice, Kevin.

(I love the way people always pick the weirdest animals!)

Phil,

Is that type of above mentioned change of orientation similar to gastropod torsion? :snail: Do you think the viscera and everything would have also changed as well?

These ammonite shell designs get weirder and weirder...

Colin,

Megalodon? Personally I think we are better off without those! Amazing to think they are known from the teeth alone; no other body parts have been recorded, as far as I know. Very impressive animal though.....from a distance.

John,

Good question; and I admit I am not able to answer it off the top of my head to be honest. I'll have to do a bit of research first. However, I can tell you that Nipponites is believed to have evolved from helically coiled ammonites such as is represented by Bostrychoceras. You may like to have a look at the family of ammonites known as Nostoceratidae, these contain many of the strangest heteromorphs.

I just can't imagine Nipponites growing and maintaining the same orientation. The thing must have twisted as chambers were added; the axis of orientation must have been forever shifting.

Some of these bizarre heteromorphs were not the specialised end-lineages they appear to be, some of the uncoiled or partially coiled heteromorphs in the Lower Cretaceous produced descendants with normal or near-normal coiling.

I apologise, that was not much of an answer for you.

Fujisawas Sake
Oct 06, '03, 4:48pm
Phil,

No, I think that was a pretty darn good answer. I think that torsion might betray a more direct evolutionary link between cephs and gastros. Only time will tell.

I'll have to look more up on my ammonites...

A good choice, Chrono!

You know, a couple of years back a number of beaks of animal called Provamproteuthis were recovered from the stomachs of some Cretaceous plesiosaurs from Japan. They were about twice as large as the modern Vampire squid and lived in much shallower water as the plesiosaur is not believed to have been a deep diving animal. It would be really interesting to see these animals and try and work out how, when and why the Vampire took the plunge into the dark......

I thought orientation was one of the few things we can determine accurately, by looking at the "bathtub ring" left by the cameral fluid in the chambers... I don't know the specifics for Nipponites, but I read about this in the geology library at some point when I was avoiding real work or something, and it seemed like this had been done pretty exhaustively for all the various shapes of chambered cephalopods...

Yep, I think you are right about the cameral deposits Monty. Much work has been done on this, much of which involves complicated mathematics, in which case my brain just goes into immediate shutdown. However, here's a link to one such article which deals with early ammonoids, their orientation and locomotion. You will need Adobe Acrobat pdf reader to read it though:

Origin of ammonoid locomotion by Christian Klug and Dieter Korn (2004) (http://app.pan.pl/acta49/app49-235.pdf)

And here is another, very readable, examination of ammonoid heteromorph orientation for you. It includes some nice little animations:

BODY POSITION AND THE FUNCTIONAL MORPHOLOGY OFCRETACEOUS HETEROMORPH AMMONITES by Neale Monks and Jeremy Young. (http://palaeo-electronica.org/1998_1/monks/text.pdf)

I think Nipponites is believed to have rolled as it grew as its centre of gravity must have constantly shifted before the final body chamber grew. I'm not sure what work has been done specifically on Nipponites, and I expect that most of it has been in Japan, but I'll keep an eye out for you if I find anything interesting.

When I was marooned along the backwater shores of the Chesapeake, my friends from California would want to spend all of their time searching our local cliffs and beaches for megalodon teeth! Found amazing amounts of other fossil sharks' teeth, porpoise earbones, dental bits from skates, but local megalodon finds proved elusive. They turned-up in local antique stores in the jewelry cabinets all the time, however. Alas, none of the local clay was quite old enough for exotic cephs.

Think they would be kind of similar to horseshoe crab? I know the local rockfish just loved to eat those, but I've never heard of them for human consumption. I don't know though, get the best trilobite meat, some eggs, bread crumbs, dry mustard, Old Bay Seasoning, Worcestershire, a little hot sauce... hmmm... Maryland Trilobite Cakes... :trilobit: :beer: :party:

Afflicted with insomnia, I looked up Liopleurodon ferox (great name that)

Phil

Well unfortunately the press does tend to exaggerate the size of Architeuthis. The maximum Total Length of a female specimen recorded is 13m, or 37ft. It is thought that the 1887 Lyall Bay NZ specimen that was recorded as 55ft was probably stretched out like a rubber band thus exaggerating the length. Mesonychoteuthis, the Colossal Squid, probably grows larger than Architeuthis though whether we will ever catch or photograph such a fully mature beast is another matter entirely.

For more information, please check out Steve and Kat's Giant and Colossal Squid Factsheet:

PS, any chance of seeing your sharks teeth, Erich? They sound most interesting.

Jul 16, '05, 10:00am
Unfortunately, my teeth were donated to Master Mark Miller upon his return from Maryland back to Los Angeles, and he jealously guards them! Actually, in addition to being an accomplished blues/blue grass/country musician, he's nuts about fossils and used to volunteer cleaning them over at the Page Museum at the La Brea Tar Pits. I'm sure we can do some kind of photographic layout that I can send your way. The Western shores of Chesapeake Bay, particularly the beaches under the clay cliffs of Calvert County, are famous for their vast amounts of fossil teeth. Most of the ones we found down there were tiny, although a few that looked to be tiger shark were around an inch.

Just curious regarding squid lengths: cephalopods are extremely elastic while alive. This being the case, coupled with the fact that the only really large squid we have to measure are all dead, isn't there the chance that until we can record the reach of a living specimen (presumably seizing prey), we'll never really know their actual lengths? The 37-foot female for instance - could she conceivably extend longer than that while alive? Perhaps to 38 feet? :wink:

I don't know if anyone has read Richard Ellis' 'In Search of the Giant Squid', but he does mention that there is a theory floating around that the giant squids washed ashore were only teenager squids and that the adults might possibly be something like 200ft. Wouldn't that be fun?
