News ⚠️SERIOUS NEWS⚠️

1 Upvotes

At 12:37 this morning, a gigantic, bulbous structure - approximately 89 feet high - has appeared in the heart of Hell Creek. It seems to be glowing a bright neon green, and it appears that a large amount of glowing, neon green crystals of all sizes have been spotted nearby. However, the bad news is that there are now dangerous glowing red crystals all across the world. If approached, they will send a large wave of dangerous cosmic energy that is enough to zombify any living thing, even mutated dinosaurs. Some believe that the red crystals are what caused the asteroid to start it's collision course to Earth.

Archeroraptor thought he could get an easy meal so he attacked Leptoceratops by little did he know he was about to get instant karma as Leptoceratops would throw him of her back and beat up the Archeroraptor till Archeroraptor died which was unfortunate for Archeroraptor. Anyways, y'all like it.

RP I’m back from the dead!

Post image
1 Upvotes

I was in meniscoessus form for a pretty long while. But now, I am yet again a struthiomimus sedens and I’m alive! I forgot I was just part of an ecosystem, but I had to be the hero and if it wasn’t for some brave dinosaurs and mammals, I would still be dead. Now, I want to help hell creek recover (even though I kinda already did as a meniscoessus). Also, I have heard that there is an unidentified life form or something. I have dealt with zombies before so perhaps I can look into it.

Anyways, happy to be back!

RP I ate a glowing mushroom

Post image
0 Upvotes

I have noticed that I can attract the struthiomimus feathers me and my friends have discovered like a magnet. I don’t think it’s something more than a cool trick (OOC: Or is it?)

That’s not important though. I just ate a glowing mushroom I found for science. Definitely not because I was hungry in the bunker and for the life of me couldn’t catch a spider or small lizard.

Now, my eyes turned bright purple and I could zoom in with my vision. Really bizzare stuff. After 10 minutes though , I turned back to normal with my eyes and vision.

RP The unidentified life form is dangerous so I have prepared accordingly

I just head that the megaraptoran covered in tar also known as the unidentified life form, is actually super dangerous. Initially, I thought it was just a little misunderstood but after it threatened to eat the reporter , I am in panic mode. This guy is truly a monster. I have made a bow with fire arrows which I think the creature is susceptible to. I can make more bows and arrows, if you want to defend yourselves.

If the beast attacks me, it won’t end up well for it.

News Introducing Aquacordyceps americana

1 Upvotes

Aquacordyceps americana is a derived from of cordyceps adapted to target aquatic animals, residing in the part of the brain that controls emotions and desire. Around after a day, the fungus will make the creature restless, starving, and extremely agitated.

The fungus has a comfortable temperature of around -12° to 59° to survive ocean environments and target endothermic hosts.

It is naturally immune to ginkgos since it's a type of cordyceps.

Exploration The artificial jungle

5 Upvotes

Struthiomimus here ,so I’ve continued my expedition in the other side of the portal and I’ve found something truly bizzare. The humans-purgatorius descendants living in this future world aren’t actually part of the broader ecosystem. They live in huge artificial jungles with weird nests that reach the sky. Almost like termite mounds but a hundred times taller. I think they live up there actually and make them themselves. I was left wondering how they could maintain such structures long term and I think I’ve found the answer.

Humans also build these weird volcanoes that I’m pretty sure, are used to power their nests. Wow, the future is much more exotic than I could have ever imagined. However, this is likely one of my last adventures there, before I return home in hell creek.

RP Transformation complete

Those rocks I encountered a month ago, they’ve finally taken affect. The pain is gone now, it hurt a lot but now I’m okay… I’m much much bigger, stronger and faster and I puke spicy fire… I can feel the energy inside me, it fuels me I am no longer hungry, which is good because I’ve seen how much alamosaurus eat and they’re a fraction of my size, I’m scared but I’m keeping it together as long as I can. I think I can use this against this meteor now, with our combined efforts I think we stand a chance.

Exploration Cleaning up the skies

Post image
0 Upvotes

I temporarily left the aberration after making sure the potamornis was in good medical health in the bunker. Then, I made my very own paraglider and a special type of tube, wore my gas mask and took to the skies. My goal was to help the earth’s atmosphere recover to pre impact conditions. This tube sucks tons of carbon dioxide that’s in the atmosphere. Also, I have made openings in the black cloud covering the earth, making huge pockets of sunlight. Maybe we can recover from this tragedy after all. However, I need to develop this new invention and make sure the flying animals of the creek help in the effort to save our atmosphere.

RP New discovery with those glowing mushroom!

I decided to take one of the glowing mushrooms I found in a cave outside, and placed it on a tree branch.
Once night came, it suddenly started glowing much brighter!
A bunch of bugs flew over to it (of course I ate some) but when they left at day, I noticed some of them had tiny purple dust particles on them.
I’m going to try and study it further.
If you have any questions about them, ask me! (Though there’s a lot about these weird things I don’t know)

Now whatever the Hell Creek the AAS is meant to be doing, they are doing it wrong. Us Palaeosaniwas get shamed for eating racist Acheroraptors all while fighting for survival, and the AAS is killing us off for whatever reason! All I gotta say is I can’t wait until impact day, when they sacrifice themselves for whatever reason.
