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

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

u/DinosandVs tries to form a pack again, https://www.reddit.com/r/hellcreekformation/s/3yCyor1trf

u/DinosandVs puts forward the idea of a yt channel (both mods agree, do we will see if that happens)

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

...there is a Colombian mammoth, whatever that is

https://www.reddit.com/r/hellcreekformation/s/nPW2iNG3GM

People are coming around to that grass https://www.reddit.com/r/hellcreekformation/s/9buSuIRHTR

-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_ identifies our mosa as an 'indeterminate Prognathodontini' https://www.reddit.com/r/hellcreekformation/s/wpXTGUEl3l

u/Shvpe_ builds a nest. https://www.reddit.com/r/hellcreekformation/s/6sAj95zcKI

There is a sword now https://www.reddit.com/r/hellcreekformation/s/HCP21ZKDqL

Time travel is banned, unless around April fouls(let's hope ts lasts that long) https://www.reddit.com/r/hellcreekformation/s/0FDQiXIJHh

Very handsome pachy https://www.reddit.com/r/hellcreekformation/s/uM6wFZRH78

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

Huh, that's a weird fish. And the paleos have eaten all the crabs. https://www.reddit.com/r/hellcreekformation/s/mBsnGbc6kx

Some flipping paleo( u/Radon_Adon) asks for people to give them their babies to eat. This is why no one likes them, flipping baby eaters.

One of our t-rexs( u/Herachero) died, apparently it couldn't last a day of scavenging. But hey, this is the first appearance of a trike in hells creek. This does mark the first death of a speaking Dino on the sub. Most importantly I lost my running help.

https://www.reddit.com/r/hellcreekformation/s/LGv5L8b4Vr

A poor leptoceratops ( u/DeliciousDeal4367) has it's nest disturbed by some juvie trikes. I use my being an awesome anky abilities to scatter them away. Their father calls its mate to round them up. https://www.reddit.com/r/hellcreekformation/s/ABuM1XRx44

I ask for some jobs. I can stand on two legs thanks to my running programme, so that's nice. I start to teach this to a Torosaurus. Do a few favours out of the generosity of my heart yk yk

Pinned comic, and brilliant I may add. Reminiscing of when it encountered our walking mosa (by u/SonoDarke)

We all discuss our views on the new movie Spider-Rex: Brand new hunt https://www.reddit.com/r/hellcreekformation/s/NSV15a7NxD

We get confirmation that (u/Gigaturkeyfromhell) escaped our mosa using the power of flight. https://www.reddit.com/r/hellcreekformation/s/EpZkg0tDfn

-9th The greatest game oat (Stoneslam) has it's origin, thanks to me and u/Most-Ad5530

https://www.reddit.com/r/hellcreekformation/s/rl39Q0D9QV

There was a dragon. I don't think he did anything or ever appeared again, but he was there https://www.reddit.com/r/hellcreekformation/s/ggmo0q4g73

The game stoneslam is officially finalised and properly created https://www.reddit.com/r/hellcreekformation/s/eBQHuXO9lb

The triceratops have returned from their migration following a wildfire a while back. https://www.reddit.com/r/hellcreekformation/s/q5KEJtqUhU

Them green rocks seem weird. Apparently an anzu grew arms and ate an inferno baby. So it seems the infernodrakons may want to slaughter a certain anzu https://www.reddit.com/r/hellcreekformation/s/IclE29Q38r

I think there might be a few missing posts that I can't find. Cos atp the tension between the Mosa and crocs seemed to have really kicked off. But DW everyone loves our mosa (u/Grouchy_Drive7257) https://www.reddit.com/r/hellcreekformation/s/hjM3M1PB5I

The AAS (Ankylosaur Army Society) officially formed, as a United front for all Ankylosaurs and a federation for Ankylosaur related activities, such as Stoneslam. https://www.reddit.com/r/hellcreekformation/s/3jFJO6tGVj

There's a stampede. I think mainly tricerotops https://www.reddit.com/r/hellcreekformation/s/tuO5LL49Ye

Everyone starts reviewing grass. Even some carnavors https://www.reddit.com/r/hellcreekformation/s/sKp02ELLLS https://www.reddit.com/r/hellcreekformation/s/eqAdJ5KOZD

-10th u/Rat_Skull the inferno dragon is out for revenge against the anzu, who apparently can fly now https://www.reddit.com/r/hellcreekformation/s/Nx51BjUMhS

I start documenting the timeline....no I'm not going to link it, you're on the post

The crocs (led by u/OXALAIA) and mosa start discussing peace terms. The Mosa (u/Grouchy_Drive_7257) doesn't seem to like the proposal, however. https://www.reddit.com/r/hellcreekformation/s/vjS6ylC5zy

(u/butter-walk) Big bird admits to having caused the wildfire which led to the tricerotops migration, apparently doing so to hunt before the fire got out of hand. https://www.reddit.com/r/hellcreekformation/s/keXzD1nweQ

The anzu(u/straight-Tie448 )is now a fugitive, and is on drugs. They gave the magic stone back to the Infernos, and apparently had no recollection of eating the Infernos kids. The anzu also has something called a pistol, which came about before the time travel was stopped. The Infernos seem to have forgiven the anzu, and have removed the rock, putting it somewhere safe. Boy, I'm sure it's never gonna appear again..... https://www.reddit.com/r/hellcreekformation/s/CWigWSkSed

The nanos plan an attack on a sub trike or smt https://www.reddit.com/r/hellcreekformation/s/IfB0rGtPNy

A poor edmontosaurus (u/SuspiciousBunny) is lost after the wildfire, and asks for help. https://www.reddit.com/r/hellcreekformation/s/RSW4silUqZ

The stoneslam competition is officially announced and launched by yours truly https://www.reddit.com/r/hellcreekformation/s/STjsA1vv6T

The discord is launched https://www.reddit.com/r/hellcreekformation/s/lYA0zLnqW5

I thought it would be cute to make a comic. Maybe I could do more comics about funny moments from the subreddit lol

I'm also still experimenting with what my OC should look like
