Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: After the events on 6/11/20██, SCP-XXXX has been moved to underwater site 560. It's containment chamber should be approximately 20 x 20 x 20 meters due to its continuous grow and already colossal size. The walls should be reinforced with 20 cm carbon steel covering most of the chamber. On the floor should be at least a 50 cm carbon steel layer.
Since SCP-XXXX breached its containment chamber, the new underwater chamber will be left unused until SCP-XXXX is back into containment. The containment chamber must be sprayed with high doses of Acetone, Xylene and Toluene, before SCP-XXXX goes back into containment. These sprays have to be added into the containment chamber to keep SCP-XXXX from trying to breach it again.
No personal ((except D-class)) are allowed to come into contact with SCP-XXXX under any circumstances.
Description: SCP-XXXX is a large dinosaur like creature. When last measured it was approximately 4 meters in height and 9 meters in length, though these measurements soon deemed false since SCP-XXXX grows up to 5 centimeters per week. SCP-XXXX has eight legs, and has venomous sacs on each one of its 386 spines on its back. These spines can paralyse and on its worst make an adult male severely sick, but the vemom is not fatal. The end of the tail is split into two.
SCP-XXXX's skin has a vibrant green and blue skin. On its back walk 5 rows of long red spines, which are venomous. SCP-XXXX is noticed to have black spots all over its eight legs and neck. The ends of it's tail have a strong cyan color, just like the paws of it. It has long nails, which are approximately 19 centimeters long. The head from SCP-XXXX is made from strong material, most likely bone. Unlike the rest of the body from SCP-XXXX, the head is a darker purple and blue.The skin of SCP-XXXX is similar to that from a tank, but has the texture of a reptile.
SCP-XXXX is noticed to have extremely strong jaws with no teeth, capable of crushing skulls and bones in mere seconds. SCP-XXXX's diet consists out of bones, Stones and plants. This is also to be thought to be one of the reasons to how it survived the 5 mass extinctions, another reason being that it lives most of it's time underground in the cave system that it has build up over the millions of years.
Although SCP-XXXX is a herbivore there are several incidents were it killed and ate personal and civilians, due to provocation of SCP-XXXX. Due to these incidents, as stated before, no personal are allowed to come in contact with SCP-XXXX anymore.
SCP-XXXX is estimated to be nearly 65 millions year old and born in the late Cretaceous period with other kinds of it's species. Although scientists aren't sure yet, it is believed that SCP-XXXX eliminated all of it's other kin, but this is yet to be determined. SCP-XXXX is also thought to be family from the Ankylosaurus (Ankylosaurus magniventris) due to some similarities of appearance and DNA.
SCP-XXXX is an extremely good digger, having dug out it's last containment chamber, and breaching it. SCP-XXXX can reach speeds up to 300 KM/H on the surface and dig up to 180 KM/H.
While studying SCP-XXXX, scientists believe that it remembers its entire existence from the day it was born, having memories of almost every event in history. It depicts this in its wall carvings, as example; on the date of █/██/████ it carved a nuclear explosion, most likely being the Nagasaki nuclear bomb from WW2. Another example is a carving from a large pile of skeletons, referring to the Bubonic Plague. All of these carvings have one single thing in common; in each one of them is carved on the side a half animal half human. Dr ████ linked it to the Paleolithic religion.
Addendum:
XXXX 1
█/██/████, SCP-XXXX has been carving several paintings into the walls of its containment chamber in site [REDACTED]. These paintings are recognized to be similar to cave paintings from 300,000 to 50,000 years ago. Most of these paintings are from a half animal, half human creature. Another painting SCP-XXXX carved into the walls was a painting of a group of people, worshiping a creature similar to SCP-XXXX. The most recent carving from SCP-XXXX is an sphere, similiar to earth, with fire around it. The scientist team is still trying to figure out what this exactly means and which historical event it is, if it is an historical event at all. Dr ██ believes it refers to the Armageddon, the end of the world.
After the painting of the sphere had been carved, SCP-XXXX breached it containment in site [REDACTED], on the date of █/██/████. It has been out of containment for more than 24 hours now.
SCP-XXXX's location is still unknown, but there were sightings of a large, vibrant colored creature walking through the ███████ █████ █████████ ██████ ███████ in██████. One MTF has been send towards [DATA EXPUNGED], but returned without any information, or SCP-XXXX.
XXXX-2
Several MTF's have been sent underground and on the surface, but they have yet to be successful. While sightings start to increase, the Foundation still fails to contain SCP-XXXX. One of the MTF teams did find SCP-XXXX, but it fled the area, taking the torso from Agent ████ with it. It was later found in one of the caves, marked with unknown symbols, glowing a vibrant blue.
