Per 
Special Containment Procedures: SCP-XXXX is to be under constant surveillance by a minimum of 5 Multipurpose Foundation Drones (MFDs) at all times.
(SCP-XXXX is containable, but containment is deemed too risky (see addendum 01). Multiple other measurements are being taken to lower SCP-XXXXs danger level as much as possible. SCP-XXXX is to be monitored by no less than 5 camera drones at all times. Additionally, 2 drones equipped with Class F turrets1 and 3 drones equipped with amnestic gas dispensers are also present. All drones must remain between 30 to 40 meters away from SCP-XXXX at all times. If SCP-XXXX is spotted by a person or gets within 1 kilometer of civilization, drones will open fire towards SCP-XXXX-1 to draw the attention of it and all instances of SCP-XXXX-2 away from the person(s) and/or civilization. A potent amnestic gas will be released in the area if deemed neccesary. The internet must be checked once every 2 days for footage of SCP-XXXX, which will be removed upon discovery, along with the uploader and potential viewers of the footage being tracked and administered Class B amnestics.
If the location of SCP-XXXX is lost, procedure MEG-101 must be initiated until SCP-XXXX is located (see document 1.XXXX). Neutralization of SCP-XXXX is considered high priority due to the threat it may pose, especially if additional SCP-XXXX-2 instaces are allowed to manifest. An effective method to terminate instaces of SCP-XXXX-2 is currently under development. Any change in behavior from SCP-XXXX-1 must be reported to personnel with level 4 clearance immediately.)
Description: SCP-XXXX-1 is presumably a member of the previously thought to be extinct species Carcharocles megalodon. It is estimated to be a male, approximately 25 meters long, with an estimated weight above 60,000 kg. It is covered in multiple scars and other wounds, presumed to originate from battling against targets during Sharktooth Events. SCP-XXXX-1 has the ability to ''swim'' through the air, with its movement observed to be identical to that of when SCP-XXXX-1 is underwater. On seemingly random occasions, SCP-XXXX-1 will initiate a Sharktooth Event. During a Sharktooth Event, SCP-XXXX-1 will find its way towards the nearest ocean and dive underwater. SCP-XXXX-1 will then proceed to look for a mature shark, henceforth referred to as targets. Upon discovery of a target, SCP-XXXX-1 will rapidly accelerate towards it, attempting to devour it. Should a target attempt to resist, SCP-XXXX-2 instances will attack and/or otherwise overwhelm the target. 1-3 hours after the devouring of a target, SCP-XXXX-1 will expunge an instace of SCP-XXXX-2 from its mouth. Whether or not SCP-XXXX-1 prefers certain species of targets over others is unknown.
SCP-XXXX-2 are anomalous entities, identical to various species of sharks. The lenght and weight of instances seem to vary between each instance. Upon manifestation, an SCP-XXXX-2 instance will take up the form of the latest target devoured by SCP-XXXX-1. Instances of SCP-XXXX-2 are able to swim through the air, identically to SCP-XXXX-1. SCP-XXXX-2 instances will surround SCP-XXXX-1, forming a natural barrier around it. When any sort of aggression is made towards SCP-XXXX-1, SCP-XXXX-2 instances along with SCP-XXXX-1 itself will target the source and attempt to terminate it, usually by biting and/or ramming. SCP-XXXX-1 and instances of SCP-XXXX-2 display high levels of aggression, but do not appear to require nutrition. The reason behind this aggressiveness is unknown. As of █/█/████, 41 instances of SCP-XXXX-2 are present, which are the following:
- 3 Prionace glauca (Blue shark)
- 5 Carcharias taurus (Sand tiger shark)
- 3 Carcharhinus longimanus (Oceanic whitetip shark)
- 4 Isurus oxyrinchus (Shortfin mako shark)
- 5 Alopias vulpinus (Thresher shark)
- 6 Carcharhinus leucas (Bull shark)
- 7 Galeocerdo cuvier (Tiger shark)
- 8 Carcharodon carcharias (Great white shark)
Currently, no method of neutralizing individual SCP-XXXX-2 instances has been discovered. Whether or not SCP-XXXX-2 instances can devour targets and expunge more SCP-XXXX-2 instances is unknown.
Addendum 01: On █/█/20██, containment of SCP-XXXX-1 was attempted. While containment was successful for the following █ minutes, SCP-XXXX-1 managed to breach containment with assistence of multiple SCP-XXXX-2 instances, additionally causing █ containment breaches, most notably from SCP-████, and a total of █ casualties. Further attempts to contain SCP-XXXX are not to be repeated. Class updated to Archon.
Addendum 02: Due to the constantly increasing number of SCP-XXXX-2 instances, more attention has been directed towards neutralizing SCP-XXXX-1. Neutralization of SCP-XXXX-1 should preferrably occur before over ████ instances of SCP-XXXX-2 have manifested. Should the current amount of SCP-XXXX-2 instances rise above ███████, it will be considered an SK-Class Threat-to-Humanity scenario, and neutralization will be top priority.
Addendum 03: On █/█/20██, an interview was conducted with PoI-XXXX, believed to be responsible for the creation of SCP-XXXX-1.
Interviewed: PoI-XXXX
Interviewer: ██████
Foreword: PoI-XXXX was asked to detail potential knowledge related to SCP-XXXX and/or the creation of SCP-XXXX-1. For clarity, PoI-XXXX will be referred to as Dr. S for this interview.

Closing Statement: Following the interview, PoI-XXXX was administered Class-C amnestics. MTF Omega-14 (''Super Stars'') were deployed to confiscate all blueprints to 'the de-fossilizer' and to drop off PoI-XXXX outside his home, where he was retrieved. The remains of the de-fossilizer were found and taken to Foundation custody for examination.
Following the examination, the remains from the de-fossilizer were deemed non-anomalous, however, they are currently being stored in Site-██.
Addendum 04: On ██/██/20██, SCP-XXXX-1 attacked an apartment building, resulting in ██ casualties. Nearby Multipurpose Foundation Drones opened fire towards SCP-XXXX-1, bringing its attention away from civilians. Class-A amnestics were remotely administered to local civilians, evidence left behind by SCP-XXXX-1 and a cover story of an anomymous terror attack taking place was relayed to local media and local authorities.
