That isn't very much when you consider vultures and condors routinely soaring from sealevel to +20,000 feet. That is a millibar difference of 300-400.<br /><br />Large Teratorns and Condors with 12 to 18 foot wingspans were common until 12,000 years ago. Actually, the majority of the large pterosaurs and birds were turkey-sized with wingspans of 20 to 30 feet. This is actually the norm, not the exception. Today's birds are depauperated. This is most likely due to both the recurring remnants of cometary fragments destroying terrestrial habitats (see Victor Clube et al.) and negative modern human influence (destruction of habitat, food sources, etc.).<br /><br />The out-sized 30 to +50 wing spanned Azdharchid pterosaurs are actually not a true anomaly. They were gigantic, terrestrial pterosaurs with very thick bones and superior launching capabilities unmatched in the modern world.<br /><br />You can find more on the Azdharchids on Tetrapod Zoology or Mark WItton's Flicker.Raymondnoreply@blogger.comtag:blogger.com,1999:blog-10092066.post-77790782267671017522010-10-29T21:36:13.645-07:002010-10-29T21:36:13.645-07:00read somewhere that they think the only way huge p...read somewhere that they think the only way huge prehistoric birds could get off the ground was due to a much denser atmosphere.
