As it approached, it used its powerful wings to slow itself down and hit the ground feet first. It took a short hopping step before landing a second time. On solid ground, it leant forward, put its arms down and walked away on all fours. </SPAN></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://scienceblogs.com/notrocketscience/2009/08/fossil_tracks_show_a_pterosaur_coming_in_for_a_landing.php"><SPAN><IMG width="200" height="152" alt="Quetzalcoatlus.jpg" src="http://scienceblogs.com/notrocketscience/upload/2009/08/fossil_tracks_show_a_pterosaur_coming_in_for_a_landing/Quetzalcoatlus.jpg" class="inset right" />The landing made quite an impression on the underlying limestone mud and in the following millennia, the creature's tracks became fossilised.
