Machairodus is a genus of large machairodontine saber-toothed cats that lived in Africa, Eurasia and North America during the late Miocene. It is the animal from which the subfamily Machairodontinae gets its name and has since become a wastebasket taxon over the years as many genera of sabertooth cat have been and are still occasionally lumped into it. Machairodus was first named in 1832, by German Naturalist Johann Jakob Kaup. Though its remains were known since 1824, it was believed by Georges Cuvier that the fossils had come from a species of bear, which he called Ursus cultridens (known today as Megantereon) based on composite sample of teeth from different countries, species and geologic ages, leading to what would become a long series of complications. Kaup however, recognized the teeth as those of felids and promptly reclassified the existing specimens as Machairodus, including M. cultridens in it. The name quickly gained acceptance and by the end of the 19th Century, many species of felid or related feliform (such as nimravids) were lumped into the genus Machairodus, including but not limited to Sansanosmilus, Megantereon, Paramachairodus, Amphimachairodus, Nimravides, and Homotherium among others. This would eventually turn Machairodus into something of a wastebasket taxon, which would be rectified with the discoveries of more complete skeletons of other machairodonts.[2] In general Machairodus was similar in size to a modern lion or tiger, at 2 m (6.6 feet) long and standing about 1 m (3.3 feet) at the shoulder. M. aphanistus from the Mediterranean late Miocene is known to be rather tiger-like in size and skeletal proportions, with a mass of 100 kg (220 pounds) to 240 kg (530 pounds). It was similar to the related Nimravides of North America. The skeleton also indicates that this species would have possessed good jumping abilities.[3] M. alberdiae was contemporary with M. aphanistus in Cerro de los Batallones fossil deposits and was smaller and more primitive in anatomical features and would not have exceeded 100 kg (220 pounds).[4] M. horribilis of China is the one of largest known species of the genus, weighing around 405 kg (893 pounds). This is comparable in size to the much later Smilodon populator. Its skull, measuring upwards of 16 inches (41 cm) in length, is one of the largest known skulls for any machairodont, with only a recently described S. populator skull rivaling it in size, with the latter cat outweighing M. horribilis at 960 lb (440 kg).[5][6] The newly described M. lahayishupup of North America was also quite large; fossil humerus bones measuring 18 in (46 cm) attributed to the species suggest that this cat was far larger than a modern lion, which has a 13 in (33 cm) humerus. It is believed to have weighed 410 kg (900 lb). Until its discovery, no true species representative of the genus Machairodus had been described from North America, as they had been reassigned to other genera, such as Nimravides and Amphimachairodus. Its presence in North America suggests that either there was a widespread population of this genus of cat throughout Africa, Eurasia and North America or simultaneous instances of independent evolution in machairodonts on multiple continents during the Miocene.[7][8][9] Overall, the skull of Machairodus was noticeably narrow compared with the skulls of extant pantherine cats, and the orbits were relatively small. The canines were long, thin and flattened from side to side but broad from front to back like the blade of a knife, as in Homotherium. The front and back edges of the canines were serrated when they first grew, but these serrations were worn down in the first few years of the animal’s life. However, a skull of M. horribilis was shown to be similar to extant pantherines in some cranial characters, suggesting new evidence for the diversity of killing bites even within in the largest saber-toothed carnivorans, offering an additional mechanism for the mosaic evolution leading to functional and morphological diversity in sabertooth cats.[10] Machairodus probably hunted as an ambush predator. Its legs were too short to sustain a long chase, so it most likely was a good jumper, and used its canines to cut open the throat of its prey. Its teeth were rooted to its mouth and were as delicate as those in some related genera, unlike most saber-toothed cats and nimravids of the time, which often had extremely long canines which hung out of their mouths. The fangs of Machairodus, however, were able to more easily fit in its mouth comfortably while being long and effective for hunting.[11] Despite its great size, the largest example of Machairodus, M. horribilis was better equipped to hunt relatively smaller prey than Smilodon, as evidenced by its moderate jaw gape of 70 degrees, similar to the gape of a modern lion.[5]Species                  :Machairodus

1.Authenticity Guarantee:
Our products are guaranteed to be genuine. If you can submit a forged report through a third-party impartial institution, we will guarantee a refund. Before sending the fossils, we will use a microscope to record all the biological characteristics of the fossils as evidence (including the surface texture of the bones and the texture of the internal structure of the bones, etc.),So please do not use the reason for the counterfeit goods received in eBay’s return mechanism to refund, because this is a very serious and false accusation, we will present evidence and take legal action.
The definition of fake fossil is that it has no biological characteristics but does not include restoration and glue.
Restoration is defined as the use of natural or artificial materials to reconstruct missing parts of fossils. Natural materials include bones, tooth, rocks, etc. Artificial materials include epoxy resin, gypsum B72, etc.
2.Shipping Safety Guarantee
DHL、EMS
Our packaging is very good, there has never been any damage caused by shipping, we will record the entire package process , when the packaging is completed, a seal will be affixed, if you receive the item, please confirm whether the seal is damaged, and record unpacking process, if there is damage, we can return the goods unconditionally and refund. (This condition does not include the cracks caused by the natural cracks originally present in the fossils, nor does it include the problem of natural shedding of eggshells.)
Due to vibrations during transportation, the fossils may crack from the original crack, so I applied a thick layer of B72 to avoid this, but if this happens, you only need to use a high concentration B72, just stick them back on.
If you cannot accept this situation and may use this reason to return or refund, please do not bid it.

11. Since more than 95% of the skeleton is composed of real bones, there are thousands of natural cracks on real bones.So it is likely to be cracked due to the vibration generated during transportation. In order to avoid this situation, I applied a thick layer of B72 on the bone to avoid this situation, but if this happens, you only To use a high concentration of B72, just reattach it. We will attach B72 to you and teach you how to use it.
If you cannot accept this situation and may use this reason to return or refund, please do not bid.
12. The customs of the United States or the customs of countries around the world have routine security checks every year.That is to say, a certain piece of goods will be kept in the customs for security inspection.This inspection is mainly to check for explosives and drugs. This inspection will cause delays in delivery. DHL or any express delivery has no right to interfere with customs inspections, nor do they have the right to require customs officers to speed up customs clearance.This inspection will be delayed for at least 7 days due to lack of manpower.
If you do not agree with the above, please do not bid it.
13.Delivery may be delayed due to inspections by customs officers, natural disasters, epidemics, or other uncontrollable factors.These factors have nothing to do with the reputation and quality assurance of our sellers.Please do not use these factors beyond our control to discredit us, we will reserve the right of legal prosecution.
