X Nice Large Colorful Hyaenodon horridus 13.5” Skull 9” Agape Open Mouth SkullAUCTION ITEM Species: Hyaenodon horridus Species description: This was the largest species of Hyaenodon in North America with massive high saggital crest in back of head, long narrow snout, short neck and long body and tail. It was the top single carnivore although a number of Terrible Pigs could drive one off. This was the largest carnivore for over 20 Million years called a Creodont and it hunted alone not in packs like its smaller 3 related species . These creodonts shared a specialized dentition commonly found in meat eating mammals with shearing structures called carnassal-teeth. This one species was the size of a bear and had 1000 lbs of pressure per bite , and was more dangerous and a lot bigger than any saber-tooth cat of its time a loner).Male specimens show grinding marks on their teeth which means tooth-grinding was used as intimidation with animals. The last creodont went extinct in America about 23 MYA but lasted to the Miocene in Asia . This is the rarest fossil of the 4 species of Creodont by far. Geological strata: White River Formation Geological period: Oligocene Period 35- Early Miocene23 MYA Item location: Shannon County ,Badlands of Western S. Dakota Item description and rating1-10 *9* Pretty Colorful Highly Original Rare Largest 30 MYA COMPLETE Hyaenodon horridus Skull with Teeth Morphology. This skull is fine with great teeth with all original except a few does have repairs . The canines plus all the teeth are original. It was found whole with exception of zygos so no full breaks, and it is simply an amazing quality piece in all regards including bone quality, beautiful color , and an adult . It’s such great bone quality it was a specimen that was very healthy so it met a quick death somehow possibly by a number of terrible pigs which were bigger, however, no bite marks on the head are evident. These got as large as 15” and are extremely desirable as few are found. Some restoration on skull occurred but expertly prepped so it looks great. Back of skull, zygos and few others like back of lowers are rstored. Quality is still x fine. Since I can’t put in words how lovely this animal is even with retore it’s so nice. IM sending pictures of this specimen and some lucky guy will get a price at great cost .It’s for an investment as this piece will grow lots in value . The unusual color alone makes this a huge buy. I lowered priced wanted on this to close to cost. The great ones go for 7500 and I have one of those now if you want almost perfection . It is open mouth on a great display and it is so amazing. Don’t ask to lower price as it is worth much more to me. This is an amazing specimen for this price. These go for 8000 and I have one that is special almost all original . This one isn’t that much lower so if you want an hyaenodon this is the one. It has a great display.

He prepped this piece and amazing facets of this skeleton and skull is exceptional with most of both sides of the skull showing out of matrix except under lower jaws and the very front on one side. Dynamite bones on both with at least 75-80 % of skeleton present due to almost all full legs showing, 2 feet with hooves on all of one and few on the other with one foot and leg bones being so beautifully prepped and laid down after death.

MAGNIFICIENT ONE-OF-A KIND HUGE 12.5” DIRE WOLF (Canis Diris) COMPLETE SKULL-Species: Canis Diris (Dire Wolf) Species description: It was closely related to Gray wolf in many features but it is not direct ancestor of any species today . IT became extinct 10,000 years ago with wooly mammoth . IT was larger than Gray Wolf averaging 5 ft in length and weighing 150-175 lbs . Legs of Dire Wolf was shorter and sturdier than those of gray wolf and the brain case was smaller to than the gray wolf .This was the largest wolf ever and ate anything it wanted as it traveled in packs also to obtain food. Geological period: Pleistocene $30,000 years old this one 1 Million-10,000 species survived Item location: LEVY COUNTY , FLORIDA Item rating and description: (1-10) **10** SPECTACULAR DIRE WOLF 12.5” COMPLETE SKULL Over 96 % Original With Lowers just found recently close to where Upper was found over a year ago . I waited on this hoping the lowers would be found and it came true. Now presenting one of only a few in existence for top Perfectionist collectors only “the DIRE WOLF”-One of the most sought after fossils in the world and complete. This skull is really fantastic as the Upper is at least 95% original and one side of lower is entirely original with only a few repairs anywhere .The back of the upper is all there as you can tell by the lines and color of a little lighter brownish tint . The back of one lower is the only item that is restored except for a few spots on upper and one spot of front of one lower . I would describe this as an outstanding specimen , and with this species even 70% is very good as this is one of top specimens ever found . Only one in Florida exits, and it’s in a museum but not this quality. I debated to sell this one or not , but I do have two LaBrea wolves and will keep one for myself . This gives you a great opportunity AS you know only Florida, Alaska , and California LaBrea have these animals, and the University of Florida has only one exhibited . No other species of wolf over 11 inches long ever existed so for you doubters, it’s true . This specimen has the most spectacular teeth you will ever see that are an extremely high % of original teeth . The entire upper are all original teeth including all incisors and the one canine shows it broke off just a small amount in life so it tells a great story . This is an old male wolf with many fights under its belt . It is a spectacular color of dark brown, black and even a tincture of light spotted teeth like the incisors The lower has all real teeth except 5 incisors in the middle. It was found 10 months later close to the upper at same area and it matches as you can tell on size and color . Its mounted on a beautiful display well and I doubt if even 4 exist in the world today of Dire wolves from Florida . This is so special I will not discount as I’d gladly keep it . It does just stir me to see this creature just as much as my bear dog from Florida and Short-face Bear in my personal collection . Even the zygos are original which unheard of in any extinct mammal. The wolf id fully inflated at 6” across also .It was expertly prepped .Remember there is always a color difference in some areas due to matrix it was found . Even the teeth aren’t completely black but most all are. Anyway for you who can’t appreciate this you never will but for the few who really know this animal this is an amazing find .

These animals had a lot of physical characteristics similar and exact to Smilodon including famous saber-guards and similar sabers while smaller . They stood at over 2 ft tall the size of a large bobcat, and were more of a group predator with a close knit families as evidenced by some hoplos found together in death while overall very rare species hunting an abundant food supply of grazing ungulates including camels and oreodonts.
