My first image is that of a claw you would not see on any Trex of any age its a Nannotyannus hand claw its 4" long from South Dakota :default_clap2:

And will conclude this weeks show with another bone you will not see in any age T rex its from a Nannotyrannus

 

 

The Nano hypothesis requires quite a leap of faith at this juncture.  Superficial bone morphology is limited and now osteohistology proves that Nanos are juvenile specimens. 

In light of the new evidence, it strains simple logic to believe in a scenario with only T. rex adults and only juvenile Nanos.  Parsimony (Occam's razor) favors them being synonymous.

No it simply requires that the morphology of an juvenile Trex arm be identical to that of an adult one, and different than those of Nanotyrannus all which exist.

All nanos are juveniles.  Osteohistology is the smoking gun.

Maybe it's not clear enough but at the Field Museum there exist an Trex arm/hand which is small and juvenile in nature whose bone morphology is identical to that of larger adult Trex bones.   Then you have this other tyrannosaurid whose arm/hand bone morphology is completely different than those two. 

 

So does it start off looking like an adult, morph to a Nano morphology being a juvenile then morph again to what an adult looks like? I just dont think so.

 

Why I choose to disagree

I am not intransigent, I will happily agree as soon as there is histological evidence of an adult nano.

Evidently, great minds think alike: :P

 

“This study is another nail in the coffin of Nanotyrannus. I think it's about time to put that coffin into the ground,” Brusatte says. “Although I hold out hope that an adult Nanotyrannus might be found, at this point I'd say it's about as equally likely as finding an actual fossil unicorn in the same rocks.”  NatGeo LINK

Well I think thats flawed thinking.   Just because Jane and Petey are still growing they have to be juvenile T rex, why?  Nano's grow and we just dont known how large they get.  They could be Juvie Nanos for all we know.  If it wasn't for all the other evidence that separate Nanotyrannus and Trex I would agree but its there....Braincases that are very different, arms and hands that a different, jaws that are different are just a few examples.

And then there is the fighting dinos in a barn in Montana... the supposed Nano there has arms bigger than an adult T rex, yet it is considerably smaller than an adult t rex.  To me, this is a better argument FOR the existence of Nano than this study is for the non-existence of Nano.  I agree with the idea that just cuz Jane and others are still growing, that does mean they are young rexes. They could still be young Nanos.  This same work needs to be done on the fighting dinos carnivore.

Having looked closely at Duelers even those its 99% complete it appeared smaller than Jane so I dont think it's an adult.  Hopefully the lawsuit will be resolved shortly and it will wind up in an OPEN minded museum

I didn't realize it was smaller than Jane.  AND you got to see it/.them??!!

Thank you for the great pictures! A great way to start out the year!

i also think it’s NOT time to bury nano yet I’m not convinced yet.  
land am I the only one to look at this picture and think that the discoloration around it looks like a body outline?

Don't worry, the name can be resurrected as soon as there is countervailing evidence to say otherwise.

I got to look at it a couple of times when it was in Montana and then again at the auction in NY.   My observation is based on the skull which looked smaller than Jane but was fractured.  Could be wrong but it needs to get into appropriate hands.  He found another skeleton this summer, specifics being kept quiet.  Saw the hand claw it was a biggie...

LOL! I originally typed feathers but then decided to go with the more ambiguous body...
