arithmetic question

[Rich Coyle]

The other day I heard about a fossil of some kind of flying "dinosaur" with a 70 feet wing span. Before that the largest ever found had fifty-one feet wing span. I found the smallest adult bat weighs .05 pounds and has a wing span of 5.9 inches. The largest bat weighs 2.6 pounds with a wing span of 67 inches.

With this info is there a way to give a guesstimate of the weight of the outrageous animal?

well the ratio of the increase in weight of he lightest bat to the heaviest you quoted was 4 times approx. So working with the heaviest bat and 70 feet span would be 35 lbs + ratio of x 4 = 140 lbs . 10 stone . That's the best I can do I'm sure there is some math expert that can do better .

I think you are comparing apples to oranges, so to speak. Maybe some "egg head" has an idea of what that creature weighed by comparing what they think another flying lizard may have weighed. Who knows? Above my pay grade LOL

Nope!

67In = 5.6 Ft. so 5.6 Ft/2.6 Lb = X Lbs./70 ft. = 150.7 lbs.
We are darn close, Bullet Bumper! I just ignored the little critters....

Yeah great minds think a-like

...And I just washed the truck!

Don't worry it's digital BS so it will not splash on the truck .

How many seagulls does that equal?

Strictly speaking pterosaurs weren't dinosaurs which OP seems to have acknowledged in the quotes around the word. For those with any curiosity about matters taxonomic it's a fun area of study. Ptero's and the things that would become dinosauria diverged long before dinos were around by the strictest definitions.

Now back to your regularly scheduled debate on the likely weight of a prehistoric flying thing of truly terrifying proportions.

I found a picture that gives an idea of this monster. It looks like its neck would weigh twice as much as a man!

 

[Bullet bumper]

Just looking at that image I would say that animal would never get off the ground the wings look too small for the body and way too much forward weight . All things that fly actually have very light bodies due to special light bones . That image is all wrong .

That image looks more like something from some of my better tall hunting tales.
