Triassic

1) At the end of the Furongian (late Cambrian) and beginning of the Ordovician, the temperature of surface waters in the equatorial zone reached 43.9°C (111.02°F), which is significantly higher than today. By the end of the Ordovician, as a result of global cooling and the onset of glaciation, these temperatures dropped to 24.2°C (75.56°F), which is lower than today.

2) Both the shortest (Induan) and longest (Norian) non-Quaternary ages are included in the Triassic period. Induan was almost four times shorter than the Quaternary period, while Norian lasted almost as long as the Neogene period.

3) There are indications that fires occurred as early as the Silurian due to the spread of terrestrial plants.

4) The Karoo Ice Age ended about 260 million years ago. The next, Late Cenozoic glaciation, began ~34 million years ago with the freezing of Antarctica. During the ~226 million years separating them, the Earth maintained a greenhouse climate. Pterosaurs and non-avian dinosaurs appeared and went extinct during this interval.

5) Scorpions became the first fully terrestrial apex predators and remained so until the Carboniferous period.

6) Latimeria is a living coelacanthiform fish. The youngest fossilized coelacanthiforms were found in Maastrichtian sediments, indicating a gap in fossil record of 66 million years.

7) The last geomagnetic reversal occurred before Homo sapiens evolved.

8) Formed as a result of powerful eruptions in central Pangea about 201.4 million years ago, the Central Atlantic magmatic province originally occupied an area larger than modern Australia.

9) People began using glue and brewing beer before the Holocene epoch.

10) We still don't know when the first insects appeared. One molecular analysis suggests they may have appeared in the Early Ordovician or even Cambrian. A gap of about 100 million years is in the history of insects in that case.

And here is Rutiodon, a phytosaur from the Norian age.

This map is from a recent study (https://scitechdaily.com/when-mega-el-nino-rewrote-earths-fate-the-untold-story-of-the-largest-mass-extinction/).

It makes me suspicious that the northern landmass is shown with very cold surface temperatures when this is the moment of extinction. In Siberia (this is apparently Siberia) at that moment there were eruptions. Shouldn't there be higher temperatures there?

Hello, and welcome back to me analyzing the creatures of Dino Dan. If you haven’t seen part 1, basically I’m looking at the design of each creature along with any information given in the show and listing any accuracies or inaccuracies, along with some general thoughts on the design removed from accuracy.

Positives = Accuracies

IDK = Can’t find or tell weather that’s accurate/possible or not

Negatives = Inaccuracies

(Creatures in appearance order)

The T.rex was one thing, but this Triceratops design being this wrong is just baffling. I think aesthetic wise, it’s barely saved by the colors, but still, wow

Ahh, much better. I am bothered by the short brow horns, but this Tricera design looks simply majestic. I appreciate the correct legs BTW. Also, while I don’t like the body, the kid Tricera is the only juvenile design that looks notably cute. (Also ironic how Jurassic world had a more accurate juvi tricera, even if barley)

This is mostly the same as the last one, but I think the new colors and rough texture make me prefer it.

While I’m not one for most 2000s Spinosaurus designs, the shades of green with orange stripes are gorgeous enough to (partially) overlook that.

I never really cared for this design, the new texture and recollection removed what I liked about it. Also, it’s really weird to watch 2000s Spino designs swim.

This design is BEAUTIFUL. Hands down one of, if not my favorite Spino design of all time and prolly favorite design of the show. The really long tail and body are lovely, the head is at its finest and I like the m sail shape. I’m unsure if I like it being quadruped or think it’s just fine. I do miss quad Spino for how unique and weirdly cool it was. Only negatives aesthetically would be the colors not being as vibrant as I’d like and the croc skin, but those aside, just fantastic.

This design is fine, great colors aside, don’t really care for it. Accurate Pterodactylus designs are much more interesting.

I can’t tell if this design is bad or I’m indifferent. It’s times like these that remind me why I prefer pycnofibered pterosaur designs, because this looks like a bald vulture. That and the colors are boring now. I do appreciate the updated skull I guess.

This design is decent, I do like how long it is, but not much to not beyond that. The color scheme is interesting, but I don’t know what to think of it.

This one is really pretty, while I wish it were longer and had more of the green on it. The rest does long boi justice. Also, this one of the few Diplodocus in pop culture with a face I like. Shame it and the Corytho redesign are barely in the movie.

My opinions on this one are essentially harsher versions of what I thought about the 1st Triceratops design. Not even the colors save it (yet), despite the frosty red plates looking cool.

While the color scheme is now perfected, the design itself I’m not fond of. Mainly because I prefer the shape of straight backed designs. That and the short neck is weird.

Eew, bad, I wanna leave.

Another big glow-up, I think one’s nice, although the colors throw me off a little.

I was so upset by this as a child and I still am. The Triassic has so many cool interesting creatures, dinosaur or not, and the only creature showcased are these stupid lizard things?! At least 65 has the excuse of the Createous being overplayed! (Even if 65 is much worse in general)

Updated notes: (updates in highlights)

I noticed the running speed pointed in the one of the episodes and reconsidered the alarm call thing

I prolly should have noted the legs on the baby Rex, and after giving it some thought, the skin looks inaccurate compared to paleo art and Prehistoric Planet. I also forgot about the Rex vs Giga episode pointing out T.rex smarts.

Thanks for reading, hope you enjoyed and goodbye

History: On April 16th, 2057, a group of young cryptid hunters were scouting Lake Erie for the mystically acclaimed Loch Ness Monster. They saw a bone sticking out of the mud under the lake, and began bringing the remains to shore. They claimed to have found proof of Nessy in Erie, however, F. W. Morrison, who was vacationing in Lake Erie, heard of the news and came to check it out. Immediately, he disproved the hunters.

Nessy, according to the photos, appears to be a Plesiosaurid, what the men uncovered was Theropoda. The specimen was in extremely good shape, most of it's body present, and even mummified skin on it's hands and feet. Morrison asked to buy the specimen for 44K, to which the hunters agreed. Morrison took it back to his second lab in Omaha, where he and his colleagues studied it even more.

It had a convex muzzle, similar to the likeness of Carcharodontosauroids, and had mixed teeth, conical teeth in the back, used for gripping slippery prey such as fish, further cementing it's aquatic behavior due to it being in water, however, other teeth were serrated, perfect for slicing dense bone. The legs were evolved to stand on land, and was possibly pretty fast, meaning it was diversely semi-aquatic.

But the specimen's neural spines spiked right above the pelvis, and raised for the entirety of the tail. Meaning it had a paddle-like tail and small sail. Morrison checked the skin, and found the feet and hands to be heavily webbed, perfect for agile swimming. The torso was elongated, which meant room for an organ similar to a swim bladder, meaning it could control its buoyancy.

After the species Naviadupleovenator erieii (Sailed Double Hunter of Erie) was described by Morrison in 2058, the species officially joined the likeness of Aftoktoniasaurus and others. More paleontologists found specimens dotting the east united states' coast, and in the Atlantic. One specimen was found eternally locked in combat with a Tanystropheus (T. hydroides).

Megastropheus tribelesodus

Height: 1.5 meters

Length: 7.5 meters

Weight: 420 pounds

Age: Late Triassic (30,000,000 A.G.D.)

Group: Archosauromorpha

Family: Tanystropheidae

Megastropheus is a bizarre reptile that live along every shoreline of western Pangea. It hunts fish, placodonts, and occasionally synapsids like Tyrannodon. While larger crocodilian predators rule the rest of Pangea, tanystropheids like Megastropheus rule the coasts.

Megastropheus is more lightly built than the raisuchians, but it has adapted several features to make it more formidable than previous tanystropheids like Tanystropheus. Its long neck extends longer than the rest of its body, so it can surprise fish and other prey.

Muscles between its neck vertebrae can expand and contract, allowing Megastropheus to control the length of its neck. While extended, its neck it more fragile, but it more ideal for hunting small prey. While pulled in, its neck is stronger and it can fight larger animal.

In Megastropheus' jaws are conical, interlocking teeth. Megastropheus is an adept swimmer, and it occasionally ventures into the water to pursue prey. There it comes face to face with the native ichthyosaurs and nothosaurs.
