When I first posted a video on YouTube
featuring the origin of dinosaurs and birds several years ago, the large reptile tree (LRT, 1611+ taxa) had 500 some taxa and the video featured genera going all the way back to Devonian tetrapods. That far back was unnecessary and became outdated last year with the addition of more tetrapods to the LRT. I will do the same with the other videos as time allows.
And one more thing…
as the late Steve Jobs used to say. The above pterosaur video was updated, as well, to be more concise and informative.
and thank you for your readership.
