What are some of the weirdest fossil vertebrates?

Recommended Posts

In your opinion, what is the weirdest fossil vertebrate? 

I would like to see pictures!

 

I will start out with the Helicoprion shark!

LOL, it's the first thing that occurred to me. However, I think this is going to be an interesting topic. There are tons of truly remarkable creatures represented in the fossil record. It's actually kind of difficult to say which is the "weirdest." aplomodo's initial choice has to be in the top ten.

A lot of the therapsids were probably pretty strange-looking creatures!

Some of the palaeomerycids (like Xenokeryx pictured below) were pretty weird-looking too!

I mean...try to imagine a short-necked unicorned giraffe with saber teeth!

Sharovipteryx would be a good candidate, I reckon :P

And I'll toss one more in here!  The Cambrian fishes (like Metaspriggina below) were absolutely bizarre!

How about Platybelodon?

There are other wild-looking elephant relatives (like Deinotherium), but these critters caught my attention recently and made me sit up!

 

Here's a link to the article that I saw. LINK.

Hallucigenia is cheating, ynot!  Aplomado DID specify vertebrates and that creature, while certainly bizarre, is, at best, an onychophoran!

Now Tullimonstrum has possibilities...unless you ascribe to a recent article that claims that it isn't a vertebrate either!  Sallan, L., et al. (2017). The 'Tully Monster' Is Not a Vertebrate: Characters, Convergence and Taphonomy in Palaeozoic Problematic Animals. Palaeontology, 2017.

 

I know...I know...I'm being too blasted picky!

For a vertebrate...Helicoprion. Only ever found two tooth swirls in 4 decades. I'd like to find an attached piece of skull or impression one day that provides some perspective on the jaw placement. 

 

Otherwise....some pterosaurs. Be neat to find one of those strange articulated wings.

 

Those early chordates from the Cambrian are bizarre...if they are chordates.  My climbing friends and I have likely scrambled over Burgess Shale like fossils and never knew it.

Didn't We have one win the vertebrate fossil of the month last year?:headscratch:

Also, I remember a nice thread about it having been assigned to the verts.:headscratch::headscratch:

Or am I having another senor moment?:wacko:

Gadzooks!  Hoisted on my own petard!  CanadaWest is right...Metaspriggina is a chordate (has a dorsal notochord)...NOT a vertebrate (chordates with backbones)!

 

As for Hallucigenia, in is currently recognized as being closest to the Onychophorans ('velvet worms' like the modern Peripatus and its relatives).  This status is still being debated.

 

Okay...one doesn't have to go too far from home to get a very weird-looking beastie!  They're common (unlike Helicoprion) but they are definitely bizarre!

 

Presenting the lowly lamprey!

Amargasaurus is a bit odd.

Birds.

 

think about it.  Weird, but we are so accustomed to them.

Any of the sail-backs (dimetrodon, spinosaurus, platyhystrix, etc.) get my vote. Diplocaulus (amphibian with a boomerang shaped skull) has to be up there too

Another strange shark being stethacanthus

another odd vert are the "terror birds". They were pretty much giant chickens that were near the top of their food chain!

I gotta agree with @jpc. Birds are freaks of nature. I once had a pet parakeet that learned to mimic the phone ringing, back when we had land lines.

 

When you would go pick up the phone to answer it, she would stop and start laughing.
