Collecta's Deinocheirus beaks?

[Rossano]

Hope I am choosing the right section of the forum for this issue, and even if I am sure it has been already addressed, I tried to find it but did not succeed. Apologies.

So, this is the question. My son choose a Deinocheirus as his next one, and as we checked out the Collecta web site we found out that they produce three models, two with a duck-like beak, nearly identical in shape, and one with a cassowary-like beak, a bit different in the shape. I checked out other producers and found out that Safari's Deinocheirus has a duck-like beak, and finally the pics of the fossil rests of a Deinocheirus skull show this form, and not really something similar to a cassowary's.

So, since the main question ("what is the correct shape of a Deinocheirus beak?") looks easily asnswered, the former question rises: why Collecta made that cassowary-like beaked Deinocheirus, and giving it a top quality model?

The "duck" beak is now considered the more accurate one.
The "cassowary" beaked model is an old model that was made before the newly recovered Deinocheirus fossils that gave us a much better picture of how bizarre deinocheirus was.

The weird hump-backed duck bill versions would be the more accurate and recent versions. Of the CollectA you have the Deluxe (which would be bigger and more expensive, and also has a slightly different pose), and the Standard versions.

Here's a pretty good up to date skeletal of Deinocheirus for refrence: https://static1.squarespace.com/static/51bf1cd3e4b0a897bf54112b/t/559ea553e4b09735c5edda20/1436460373212/Deinocheirus+skeletal
