WELCOME TO JAYRASSIC PARK

Item #: SCP-XXXX

Object Class: Eucild

Special Containment Procedures: Due to the temporal nature of SCP-XXXX, active containment is not feasible. At present, temporal alteration or containment is strictly unauthorized.

Existing Foundation personnel embedded in natural history museums have no change in protocol upon confirmation of a SCP-XXXX instance.

All fossilized instances of SCP-XXXX are to be stored securely on Site 454-Ticonderoga and monitored using Class-2 Security Systems, with standard security procedures.

Carcasses of SCP-XXXX instances are to be held at Site 454-Ticonderoga’s Biological Containment and Study Wing, in Cyropreservation Floor 69. Observations are to be done every hour. Dissections and study must be approved by presiding Doctors and Site Directors. Please see Document 28 for a full list of authorized personnel.

Disinformation campaigns, including the replacement of affected fossils with grown copies from preexisting genetic material, are to be carried out at all locations with confirmed instances.

All current and planned paleontology projects and dig sites focused on the Mesozoic Era are to be augmented with embedded Foundation personnel, with at least one (1) doctor and one (1) Agent. Please see Document 21 for further instructions if you have been selected to be embedded.

If Foundation personnel are, for any reason, unable to be embedded within paleontology crew, Foundation personnel with appropriate rank are authorized, after approval by Ethics Committee, to contact the organizations of the crews/digs and recall them with appropriate cover stories. If any non-Foundation personnel have uncovered instances of SCP-XXXX, they are to be interviewed to determine the extent of their knowledge of the SCP-XXXX instance and its effects. Doctors Bakker and Horner have been authorized by the Ethics Committee to determine if non-Foundation personnel are to be authorized as Special Advisors or to be administered amnestics and returned to the general public.

For a complete list of authorized Special Advisors, please see Item Claw-32.

Description: SCP-XXXX is both an ongoing phenomenon affecting various animals spanning the Mesozoic era, various species of dinosaurid that have not existed on the fossil record prior to July 23rd, 2015, and fossils of the affected animals. The phenomenon is known to retroactively affect fossils already uncovered and placed on display in both public and private collections.

Current data indicates the most affected fossils are of: Tyrannosaurus rex, Utahraptor, Achillobator, Dakotaraptor, Apatosaurus, Diplodocus, Microraptor, Velociraptor, Megaraptor, therizinosaurus, Brachiosaurus, Carnotaurus, Deinonychus, Giganotosaurus, Albertosaurus, Acrocanthosaurus, Baryonyx, Spinosaurus, Pterodactyl, Megalodon, and Plesiosaurus dolichodeirus. For a complete list of affected species, please see Document 5.

Notable alterations to fossils include:

  • The lack of feathers/proto-feathers, especially on dinosaurs discovered prior to the widely-accepted theory that many dinosaurs were feathered. (Not sure about wording on ‘widely accepted theory’.)
  • Theropods, especially Tyrannosaurid, forming features conducive to hunting and fighting, such as the addition of fangs, sharper teeth, altered musculature and bones, and lengthened arms.
  • Approximately 80% of dromaeosauridae, especially those of Velociraptor and Deinonychus, have been replaced with a dromeosaurid resembling Achillobator - among other differences, however, the dromaeosaur possesses thicker leg bones, a more prominent “killing claw” and talons, an endocast revealing an estimated 20% increase in approximate brain size, more teeth, pronated hands, and, most prominently, scales in lieu of feathers. Nearly 40% of instances have preserved skin samples demonstrating scales and pigmentation.

Microscopic and forensic study/DNA study of all fossils show modifications at the genetic level via unknown means. For further information, please see Document 32.

In addition, SCP-XXXX instances that were displayed in museums, especially the Smithsonian, the Chicago Field Museum, the Berlin Museum für Naturkunde, and the Canadian Royal Tyrrell Museum of Paleontology, have had notes either placed near or on the SCP-XXXX instances.

These notes, often notes both typed and handwritten, are addressed to paleontologists who are either employed with, or associated with the museum they were found in.

Current graphology and forensic analysis to locate the party or parties responsible for SCP are underway. Authorized personnel may contact Assigned Doctors and Special Advisors for progress.

For a full list of notes, please see Item Talon-111.

Addendum: The following is an excerpt of selected notes.

Handwritten in cursive on the femur of an altered tarbosaurus:

Hey, Doctor Sattler, I bet you’re not laughing at my theory anymore!

Typed on a non-anomalous paper sheet 12x12, found next to an altered suchomimus:

Dear Doctor Swanson: Aweosmebro this, asshole.

Found inscribed on the crest of a parasaurolophus, via laser:

See? I was right, Marcos. Suck it down.
