...or perhaps some other teratorn (giant bird, but using big words makes me feel smart :P)?
Argentavis magnificens, which, unimaginatively means magnificent Argentine bird is supposedly the biggest bird that has ever lived. There isn't much known about it, but its wing span is estimated to be as large as 7 - 8 meters! Now, I've sculpted this and the two previously shown monsters in 1:50 scale, as I found it easier to convert numbers...I never was much of a maths guy :P. So, my models wingspan should measure something like 14 centimeters, but I did something wrong somewhere so it gets to around 11-12 centimeters or so. We could say it's not a full grown bird yet, or just call it some other teratorn - I don't think anyone would lose any sleep over this matter!
No matter the historical facts, I think a human sized bird (based on 40mm base) will fit in nicely instead of pterodactyls and could easily be used in other pulp games!
Well, anyways, thanks for looking and expect another extinct animal in next post!
