A piece of toast and a terminator.

What's the deal with Nanotyrannus? Was it ever confirmed to be its own genus? Or is it just a juvenile Tyrannosaurus?

"Nannotyrannus" based on current knowledge is a juvenile Tyrannosaurus and any support for Nannotyrannus has either been not published, lost, or completely unfounded. At this point the niche for a medium sized carnivore is hypothesized to be occupied by Dakotaraptor making even less evidence for "Nannotyrannus".

@Stan The Man: Me thinks you're looking for Cothurnocystis.

I thought no one would find that- nicely done DK.

While I was making the post I realized the book that had this thing was downstairs by my copy of Dr. Holtz Jr.'s book. I decided to publish the post anyway to see if people might go crazy trying to find such an obscure animal.

What was the largest member of the nothosaur family?

Nothosaurus itself at about 4m is the largest I'm seeing.

Nothosaurus zhangi has a length estimated between 5-7 metres depending on its proportions, with the largest lower jaw of any Triassic sauropterygian at 65 cm long, compared to the 59 cm lower jaw of N. giganteus.

Do we have any other fossils or evidence of large Cephalopods minus tusoteuthis, the Svalbard squid and dare I say it? Triassic Kraken?

Wouldn't exactly say the Triassic "kraken" is supported by any solid evidence.

You also left out Cameroceras, which wasn't exactly tiny either (in fact it's the largest known animal of the Paleozoic IIRC).

The largest ammonites we have, of the genus Parapuzosia could reach 2m in shell diameter.

IIRC Niobrarateuthis was also quite big.

Earlier I noticed this on the wikipedia article for the irish elk
Quote:
 
Early phylogenetic analyses supported the idea of a sister-group relationship between fallow deer (Dama dama) and the Irish Elk.[5][6] However, newer morphological studies prove that the Irish elk is more closely related to its modern regional counterparts of the Red Deer (Cervus elaphus).[7] For this reason, the name "Giant Deer" is used in some publications

Is it true that the Irish elk was actually an large species of red deer, rather than an giant fallow deer? Also if it is related the red deer, wouldn't that make it's common name 'Irish Elk' be more appropriate, considering red deer belong to the same genus as the Wapiti, which is also called Elk?

What happened at the end with the Amphicoelias?

What makes you assume there's been closure on it? It's been a long-lost mystery of paleontology for over a century and it still is.
