Keep in mind how slender a bird is when you remove the feathers.

I based the reconstructions on skeletals, tough I admit that I used a particularly big headed one for Torvosaurus

Torvosaurus (ML 1100):
Red: based on largest skull (~1,58m, ): ~11m
Normal: estimate for european maxilla: 12m

Mapusaurus:
Red: based on largest skull (~1,8m, from a comparison Grey posted on the appropriate tread-let´s hope it´s accurate): ~14m
Normal: largest estimate for MCF-PVPH-108.202 (fibula ~860 mm): 12,6m

I based them on the best references that I could find (not difficult in Aardonyx´ case, but very difficult for Gasosaurus):
References:
Aardonyx was based on this skeletal drawing: http://archosaurmusings.files.wordpress.com/2009/11/fig_1_-_aardonyx_skeleton_by_adam_yates1.jpg

Gasosaurus was based on this mount (unfortunately it was the best i could find, and much of it remains fiction): http://upload.wikimedia.org/wikipedia/commons/5/5a/Gasosaurus_fossil_Bishop_Museum.png


-------------------------
Now for the comparison:
One grid segent corresponds to 20cm.

First one showing some of the size estimates for Gasosaurus, ranging from 3m to 4,5m.

According to wikipedia (NL), the femur of Gasosaurus ought to measure about 42cm. One can easily see that only the green Gasosaurus can be anywere near that figure.

They are measuring ~3-~3,5m

Now a comparison with Aardonyx:

This Aardonyx measures 6m.



Here´s a version with a human for comparison.

-------------------

Of course due to the lack of data I there could be some inaccuracies on the Gasosaurus, but I doubt that it would get to 4m, and even less to 400kg. 2000lb for Aardonyx seems complete exageration as well tough.

That's pretty awesome.

Do you think you could add in megatherium in there as well?
