Richard Dashnau<p>On 08/20/2023 (last year) During a 2nd dry summer at BBSP an alligator was moving through mud in a drying 40 Acre Lake. It would move a bit, then rest. Why did the alligator move in this direction? Did it see water? Did it remember water? Birds moved easily on the mud. This gator met 2 others chased out of a deeper spot by *another* gator. Gators talked later. 90 minutes condensed into 10 minute video: <a href="http://www.rickubis.com/rick/gators_mud082023.mp4" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">http://www.</span><span class="ellipsis">rickubis.com/rick/gators_mud08</span><span class="invisible">2023.mp4</span></a> <a href="https://ecoevo.social/tags/Ichnology" class="mention hashtag" rel="tag">#<span>Ichnology</span></a> <a href="https://ecoevo.social/tags/Alligators" class="mention hashtag" rel="tag">#<span>Alligators</span></a> <a href="https://ecoevo.social/tags/Archosaur" class="mention hashtag" rel="tag">#<span>Archosaur</span></a></p>

Did you know that many theropod dinosaurs have thick pads on the bottom of their feet? Much like the paw pads of dogs and cats, these probably helped cushion their footfalls and assisted in gripping the ground when running.
