Gordodon: The Oldest Specialized Herbivore

Gordodon was a sailed-backed edaphosaurid from the Carboniferous/Permian boundary. This was not long after terrestrial vertebrates first evolved to become herbivores. Despite this, Gordodon already possessed specializations for its herbivorous diet that wouldn’t be seen again until nearly one hundred million years.

It's harder to digest plants compared to animal proteins. So Gordodon with it's herbivory was a milestone in Amniote evolution.

"Haha, I may not be able to move, but it doesn't matter! I'm inedible! I'm a genius!" "Oh no!"

@mhdfrb9971 Год назад

To think about it, all vertebrates are originally started with carnivorous diet. So Gordodon are pretty revolutionary.

@dinohall2595 Год назад

The human profile for scale next to Gordodon makes me imagine putting a leash on it and taking it for a walk around the block like a dog. Definitely a much safer pet than Dimetrodon.

@alexsantimano6443 Год назад

Not to mention it's proportionately larger head and lack of barrel chest would make fitting a lead easier than it's fellow edaphosaurids

@rianfelis3156 Год назад

Fascinating how sails were useful enough to be common then but are so rare in later periods.

@somerandofilipino6957 Год назад

These animals existed before the advent of mesothermy. Sails were a crude but workable means to capture and displace heat needed to function, try viewing it as one of many unique steps taken during the grand game of trial and error called evolution.

@IPS-bk2wr Год назад

It was much warmer back then. Their sails would’ve been perfect for cooling off, if I’m not mistaken

@AifDaimon 8 месяцев назад

I knew Gordodon wouldn’t disappoint. Excellent video! Fun fact, Gordodon is so far the oldest animal you have done a video on. Every other one has been from the Middle Permian and later.

Why does the sail have to be one or the other, couldn't it be both a means to thermoregulate and a mating display? I'm a fan of the brightly colored versions, that would be cool if they were. Huge fan of this channel. Cheers all.

@bedlaskybedla6361 Год назад

This is really awesome animal, I never heard about it before. In a late carboniferous/early permian there was a huge boom with herbivorous animals such as edaphosaurids, diadectids or some captorhinids. Diastema is really great adaptation for Gorgodon, allowing him to coexist with other big herbivors.

Technically, it isn't even a reptile. Gordodon shares a more recent common ancestor with us than with skinks or geckos.

@Eliras24 Год назад

btw i'm still baffled by how could ever survive animals with dorsal sails like these. Like, you could get fatal wounds so easily there

@Liethen Год назад

Depends. How much blood flows through it? How quick do they clot? How high is their blood pressure? Ears can get shredded without bleeding out. I figure, even if they had lots of blood vessels in their sails the fact that they are a small low-slung and probably low metabolism creature they probably clotted wounds there way before they could lose much blood.

@rileyernst9086 Год назад

I think they should have dropped a do and just had Gordon. That aside... I think true fruit is a bit overrated. Considerimg ginkgos, podocarps, yews, gnetales, seed ferns, cycads and bennitales, were all doing the same thing well before true fruit. For Gordodon, i can certainly see seed ferns and early cycad things being present at this time. Seed ferns have been found with both nuts and a more fig like false fruit(unless it was the false flower, in which case I'd suggest that fasle fruit and false flowers maybe good fodder)

@posticusmaximus1739 4 месяца назад

@andrewpaige1194 Год назад

That makes me question the sexual selection theory. Clearly there was a biological reason so many significantly sized animals, some SO distantly related(reptile/mammal, and amphibian) convergently evolved such incredibly significant huge sails simultaneously(relatively speaking), and it definitely wasn’t just “it was the style at the time”!

@baneofbanes Год назад

I personally think that at least for animals like Gordodon and Dimetrodon them suing the dials to wake themselves up makes the most sense.
