Question: Skull & Bones is a mini-series by a man that is an editor of what two comics?
Context: Shiver and Shake was a British comic magazine published every Monday by IPC Magazines Ltd.  It ran from (issues dates) 10 March 1973 to 5 October 1974, when it merged with "Whoopee! ".  As in the tradition of British comics many names of strips were a play on popular television programmes and films of the time.  Similar to "Monster Fun" later, the theme of the strips were mainly horror (albeit of a comic nature).  Indeed Frankie Stein appeared in both comics.  Borrowing from the successful "Whizzer and Chips", it was two comics in one; "Shake" being a pull-out section from "Shiver".  The main star of "Shiver" was a ghost of the same name, whilst "Shake" was an elephant.  Both had their own strips in their respective sections ("The Duke's Spook" and "Shake"), "The Duke's Spook" changing to "Shiver" after its merger.  In 1973, the comic also featured a one page strip starring stand-up comedian Charlie Williams.  Other strips in "Shiver and Shake" included: Billy's Boots was a popular British comic strip by writer Fred Baker and artist John Gillatt, later continued by Mike Western.  The original Billy's Boots was an earlier humorous series, written and drawn by Frank Purcell, which appeared in Tiger between 1961 and 1963, with a similar premise to this later series.  The later more serious Billy appeared in the first issue of "Scorcher" in 1970, and later moved to "Tiger" when the two comics merged in 1974.  In 1985 "Tiger" in turn merged with "Eagle" and the strip moved again, however just a year later Billy's adventures relocated once more, this time to "Roy of the Rovers".  New adventures were included in the weekly comic until May 1990 (later followed by reprints), before he switched to "Best of Roy of the Rovers Monthly".  The strip also appeared in annuals, including annuals for comics which had themselves ceased publication, and is still fondly remembered by fans of the "golden age" of British boys' comics.  In Finland and Sweden, "Billy's Boots" was published in "Buster" magazine.  In the UK, stories based on Billy's earliest adventures appeared in "Total Football" magazine until it closed in 2001, and Billy's story was also reprinted for a few months in the defunct Striker comic. Ed Hannigan (born August 6, 1951) is an American comics artist, writer, and editor for both Marvel Comics and DC Comics. Brachycephaly (from Greek roots meaning "short" and "head") is the shape of a skull shorter than typical for its species.  It is perceived as a desirable trait in some domesticated dog and cat breeds, such as Pugs, and can be normal or abnormal in other animal species.  In humans, the cephalic disorder is known as flat head syndrome, and results from premature fusion of the coronal sutures (see craniosynostosis) or from external deformation (see plagiocephaly).  The coronal suture is the fibrous joint that unites the frontal bone with the two parietal bones of the skull.  The parietal bones form the top and sides of the skull.  This feature can be seen in Down syndrome. Skull & Bones is the fifth studio album by the American hip hop group Cypress Hill, released on April 25, 2000 by Columbia Records.  The album's genre and style are divided into two — a pure hip hop disc ("Skull") and a rap metal disc ("Bones").  It features appearances Everlast, Eminem, N.O.R.E., Christian Olde Wolbers, Dino Cazares of Fear Factory, Brad Wilk of Rage Against the Machine, and Chino Moreno of the Deftones. Gorgodon is an extinct genus of basal synapsid.  The genus is monotypic, known only from the type species Gorgodon minutus from the Early Permian of the southwestern United States.  The only known remains of "Gorgodon" are two fossils consisting of fragments of the skull.  "Gorgodon" was described and named by paleontologist Everett C. Olson in 1962 from the San Angelo Formation in Knox County, Texas.  Based on what is known of "Gorgodon" — the squamosal, quadrate, and pterygoid bones of the back of the skull, the maxilla and premaxilla bones that make up the front of the skull, and several teeth — "Gorgodon" had a relatively large temporal fenestra and a pair large, conical caniniform teeth at the front of the jaw.  Other distinguishing features of "Gorgodon" include the fused connection between the quadrate and squamosal bones and a long transverse process of the pterygoid (a projection extending from the pterygoid bone on the underside of the skull). Mastodonsaurus (meaning "breast tooth lizard") is an extinct genus of temnospondyl amphibian from the Middle Triassic.  It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size and presumably aquatic lifestyles.  Like those of many other capitosaurs, the head of "Mastodonsaurus" was triangular, reaching about 1.25 m in the largest specimens.  The total length of the largest individuals is about 4 to .  The large, oval eye sockets are midway along the skull.  The jaws are lined with conical teeth.  Two large tusks project up from the end of the lower jaw, fitting through openings on the palate and emerging out from the top of the skull when the jaw is closed.  The body of "Mastodonsaurus" is relatively small in proportion to the large head, and the tail is relatively short.  The greatly reduced limb bones have joints that are poorly developed.  The marked reduction of the limbs and grooves on the head called sensory sulci show that "Mastodonsaurus" was an aquatic animal that rarely left water.  "Mastodonsaurus" may have been completely unable to leave the water, as large quantities of bones have been found that suggest individuals died en masse when pools dried up during times of drought.  It inhabited swampy pools and lived mainly on fish, whose remains have been found in its fossilized coprolites.  It probably also ate land-living animals, such as small archosaurs.  The fossils of some smaller temnospondyls bear tooth marks made by "Mastodonsaurus"-like animals.
