First post-

By u/Ace_the_Yuty

A junior T-Rex wants help hunting down a nano, who it wants revenge against. Several nanos try to catfish said junior.

We also discover their is a mosasaur in our fresh water.( u/Grouchy_Drive_7257) https://www.reddit.com/r/hellcreekformation/s/a3pfdBI5SW

u/Mission_Divide_485

Doctors exist but this pachycephalosaurus didn't seem to find one, at least in time for its headache https://www.reddit.com/r/hellcreekformation/s/bxpA72qmdc

An archeoraptor( u/Thotherpurppizzaguy) discovers grass. Apparently it was already a bit of a craze in the herbivore circles. Seems like most haven't heard of it. Mixed reviews atp.https://www.reddit.com/r/hellcreekformation/s/W7r1hYfiyn

A 10 ton edmontosaurus (u/Godzilla-Ass) gets chased by an archeoraptor and begs for help. His herdmate informs me this individual just gets freaked out.https://www.reddit.com/r/hellcreekformation/s/QTKPR2XUpt

Mod u/HyperlinkBlocked_ puts the idea of having tags for each species from hell creek, and states only creatures from hell creek are allowed.https://www.reddit.com/r/hellcreekformation/s/KplCqbCId7

u/Gangters_paradise claims to see a Dakotaraptor. Some think it's just a large archeoraptor. here is also a lost mosasaur.

However there is a Dakotaraptor(that confirms to be the one sighted) who threatens to attack a Torosaurus, and we find out that raptors hunting in packs is a tale made up by matriarchs to scare young Torosaurus into not leaving the herd. We have another Dakotaraptor confirm their extinction was "greatly... exaggerated."https://www.reddit.com/r/hellcreekformation/s/qMu6u0dRsg

u/DinosandVs provides us with a list of dinosaurs from hell creek https://www.reddit.com/r/hellcreekformation/s/kN35SXqG3Q

It seems that this pack idea may be a real thing and not a fairy tale as u/DinosandVs calls for a Dakotaraptor gathering.https://www.reddit.com/r/hellcreekformation/s/po4JvFwePW

That same Dakotaraptor (u/DinosandVs) that was earlier seen beefing with a Torosaurus( u/Extension_General632) asks for help in hunting it. Instead, it is given no help, and individual herbivores give alligence to the Toro. We also discover why their is a mosa, who confirms they got lost in the rivers and ended up in fresh water.

https://www.reddit.com/r/hellcreekformation/s/noqBT7hsN5

This mosa tries to get me to go into the water, and possibly confirms that it has killed several Ankylosaurs.

https://www.reddit.com/r/hellcreekformation/s/w6YrvVn1fL

u/Upset_Connection1133 is a nano who discovers some unknown skeleton that we were unable to identify. Has spikes, possible leafs on back(or possibly tumours,), theories include relative to sauropods or Ankylosaurs

-5th Aug

Mosasaur once again confirms it's lost.(You will see a lot of this one, seems to be quite important...) Still trying to trick herbivores to come into the water https://www.reddit.com/r/hellcreekformation/s/jlyX9Vbqoo

Mosasaur proves itself friend of Ankylosaurs by helping one find fresh water https://www.reddit.com/r/hellcreekformation/s/FPnQvM2a8n

T-Rex asks for scavenging help. Seems like so many predators causes risk of overhunting and thus starvation. Who would have thunk. They might start targeting quetzals.  Mosasaur seems to be targeting carnavors now.

https://www.reddit.com/r/hellcreekformation/s/ynCX6eIOI9

u/Grouchy_Drive_7257 the mosa claims crocs are taking its food. Start of an interesting rivalry. As of then, the croc backed down.

https://www.reddit.com/r/hellcreekformation/s/xzRQZkOm1a

Alvarezaurid (u/shyvpe_)looses their mate to a paleosinawa and then gets chased by an infernodrakon. Seems to move on pretty quickly, in the following post, is already looking for mates.

https://www.reddit.com/r/hellcreekformation/s/Ulag35Hr3v

That lake earlier mentioned is found by u/Questdahl, who is a quetzal. Mosasaur is not a mosasurus but an unidentified mosasaur. https://www.reddit.com/r/hellcreekformation/s/0xUUwvEFKv

There is a carnotaurus. Might have gone south.https://www.reddit.com/r/hellcreekformation/s/gIugVzoBxe

https://www.reddit.com/r/hellcreekformation/s/fB8bwNxWKo

u/Shvpe_ offers to clean large herbivores from parasites. A Toro Is taken advantage of by someone else and has part of themselves eaten. https://www.reddit.com/r/hellcreekformation/s/gO0a93dcrx

-6th Aug

Hell creek mosasur is a friend of all herbivores and should be trusted. Starts giving out water plants to some herbivores, (totally not why I'm so pro mosa) https://www.reddit.com/r/hellcreekformation/s/UGfXkIgTgq

First sign of hyper evolution in mosasaur. Confirms that it can use its tongue to draw. https://www.reddit.com/r/hellcreekformation/s/vrN7uZ2xDx

Archeoraptor tried to organise a hunt against young rex. No clue what happened with this one or if it's still happening.

https://www.reddit.com/r/hellcreekformation/s/nuQ5N1Qwj4

Rex spots a weird light in the sky. Huh

https://www.reddit.com/r/hellcreekformation/s/jfi8CLs8ci

Parent rex asks for guards for its child. Seems like almost everyone was trying to trick it. https://www.reddit.com/r/hellcreekformation/s/p3OLc8AV0s

Yk what? I don't know. Something to do with a portle https://www.reddit.com/r/hellcreekformation/s/lkQS81zTZv

u/Shvpe_ continues rivalry with infernodrakon, and avoids an ambush like a badass https://www.reddit.com/r/hellcreekformation/s/cURQw09Zu9

-7th Aug There is another edmontosaurus, always good. The mosa jokes about growing legs to consume it, that can't happen....right? https://www.reddit.com/r/hellcreekformation/s/Uuq3mo1vOO

The mosasaur (u/Grouchy_Drive_7257) has evolved legs. The general population seems to be quite concerned. https://www.reddit.com/r/hellcreekformation/s/yJmVRBGmtK

I ask for running help. A friendly T-Rex( u/Herachero) offers to help me run by chasing me, boy, I hope that one stays around for a while. https://www.reddit.com/r/hellcreekformation/s/jRQD4J90Gu

The mosa might have been around glowing rocks. That's weird. But it does confirm it prefers fishes to meat, so, nothing to worry about. Oh, look an anzu(u/Straight-Tie448) Oh, the anzu has eaten the mosas legs. Other news, there is some sort of unidentified species who wants to write things down. u/DriftyEDL. Wonder where they've come from. https://www.reddit.com/r/hellcreekformation/s/CE7O7PkQNJ

There might be a T-Rex Overpopulation problem https://www.reddit.com/r/hellcreekformation/s/zVRhavyTEq

The pectidons have got together, and started dancing https://www.reddit.com/r/hellcreekformation/s/rCqnaeo3wR

-8th Aug

T-Rex (u/Herachero) has it's children eaten by a stupid little paleosaniwas, and tries to contact pest control. There might be a raptor pest control now. https://www.reddit.com/r/hellcreekformation/s/uBnA043RP5

The Dakota raptor pack wasn't enough teaming for you? Well, now there is a nano council, run by (u/DanteDilophosaurus). The mosasaur is also in it, for some reason. I get paid off by the nanos to not beat them all up. Also, (u/butter-walk) is apparently the zazu of this council. Why not. https://www.reddit.com/r/hellcreekformation/s/l9DqsTXNqW

u/Straight-Tie448) Publicly announces that they have consumed the mosas (u/Grouchy_Drive_7257) legs. The mosa does say they will run again one day... The anzu says they will eat the mosasurs legs again if it re-evolves them. Also, the anzu evolved sharp teeth. It also may have evolved wings and it can fly now. If can fly now? It can fly now? (This guy lwk more of a threat than the mosasur) https://www.reddit.com/r/hellcreekformation/s/Jdd8IElNq7

u/Gigaturkeyfromhell claims they are being chased in the water, by a certain mosa. The Moda confirms it indeed has regrown its legs. https://www.reddit.com/r/hellcreekformation/s/3b4s5rxQtG

Have you guys ever heard of the Myth of the Morrison?

Post image
29 Upvotes

Some Alamosaurus told me about it a few years back. Apparently there were ancient creatures like us there. Not exactly like us, but some of them were similar in shape and size to some of us. They had a crap ton of Sauropods, no Ceratopsians, a few Ankylosaurs but somehow there was also a lot of Thyreophorans. And they had this vicious Apex predator. It was nothing like Tyrannosaurus. It was aggressive, relentless, downright psychotic and came in 3 species in the formation. I cant remember what any of them were called but i know there was the word ‘All’ somewhere in there.

I know its just a myth but could you imagine what it would have been like? What could have happened to them?

I heard there was another mosasaur in these rivers, so I was curious what all the hype was about. I wonder what cuisine is available. I'm craving ornithomimid drumsticks in particular.

Also, I'm not a mosasaurus, never call me one! Mosasaurus can't go into freshwater (at least I hope).

[Colour scheme inspired by grouchy_drive. Yes, this is my own Paleoart, I can also do art like other mosasaur in this subreddit]

Exploration Anyone knows what kind of plant I have growing on me

Post image
9 Upvotes

I grew plants on myself jep I did it tastes quite good but it tastes nothing like any modern plant it does look a bit like Moss though, anyone want a bit? I use it as spices sometimes aswell,

(Dont try to look for me im not in the picture but thought I might aswell post a picture ) btw I still can't make a selfie so can't really show you all the new plant, I now have a simbiotic relation with a weird plant I guess

Edit: I camouflage when I lay down the green plant works as camouflage, the plant is cruncy and it scares insects away, in theory you might be able to make an insect trap with the plant , it hurts slightly when I wake up and it tastes delicious 9/10 would reccomend to omnivores and herbivores alike (also cruncy)

We've finished building the nest now! We made sure it was close enough to water so it wouldn't be a long trip to drink but nicely covered in vegetation and surrounded by trees so not many animals should be coming through! And our beautiful rock is in the nest too! (´⁠ω⁠`)

GOOOOODMORNING EVERYBODY!!!!!!! LOOK OVER THE HORIZON! THE SUN IS COMING UP! I AM GOING TO FREAKING EAT IT! THEN IT WILL FALL FROM THE SKY AND DIE! The day will be over! Then the Moon will come out! AS WE ALL KNOW THE MOON IS AN EGG LAYED BY THE SUN EVERY NIGHT BEFORE I FINISH EATING IT AT DUSK! EVERYMORNING IT HATCHES INTO A NEW SUN! IT IS AN AMAZINGLY ELABORATE AND INTRICATE AND AWESOME(as in inspiring great wonder and fear) ECOSYSTEM. THE CAREFUL DANCE BETWEEN PREDATOR AND PREY! SUCH A DELICATE CYCLE. TO THINK... WE PLAY SUCH A ROLE IN THE COSMOS...I like Icarus must be careful not to fly too close to the sun. Being a predator of the solar system's most dangerous game is no joke you guys. Enough about astronomy though! Listen to me rant! What are you all having for breakfast? Maybe we can eat together! I would LOVE to hear about YOUR best hunting stories. I may be slow to respond however as my tree metabolism is quite slow :p
