Agnotherium
''Agnotherium'' is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae ("bear dogs"), which has been found in Western Europe, and possibly Northern Africa, and lived during the Late Miocene epoch. Despite only being known from fragmentary remains, the genus notable for hypercarnivorous adaptions, which have been said to represent the "apex" among its family.Morlo M, Bastl K, Habersetzer J, Engel T, Lischewsky B, Lutz H, von Berg A, Rabenstein R, Nagel D. 2020The apex of amphicyonid hypercarnivory: solving the riddle of Agnotherium antiquum Kaup, 1833 (Mammalia, Carnivora).Journal of Vertebrate Paleontology 39(5):e1705848 DOI 10.1080/02724634.2019.1705848. History and naming The genus ''Agnotherium'' was created by Johann Jakob von Kaup, based on a single molar (HLMD Din 1143) found in the Eppelsheim Formation, more well known as Dinotheriensande, located in southwestern Germany. Kaup, who described many Eppelsheim mammals, including such famous ones as ''D ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Thaumastocyoninae
Thaumastocyoninae is an extinct subfamily of amphicyonids, large terrestrial carnivores, which inhabited what is now Europe during the Miocene epoch. The subfamily was erected by Hürzeler (1940), and is defined by the complete suppression of m1 metaconid, reduction of the premolars, except the p4, which is reinforced, and the oblique abrasion of the teeth, and the possession of hypercarnivorous tendencies. Thaumastocyonines are poorly known, with only about 65 dental specimens, most of those isolated teeth, being known as of 2020,Morlo M, Bastl K, Habersetzer J, Engel T, Lischewsky B, Lutz H, von Berg A, Rabenstein R, Nagel D. 2020The apex of amphicyonid hypercarnivory: solving the riddle of ''Agnotherium antiquum'' Kaup, 1833 (Mammalia, Carnivora).Journal of Vertebrate Paleontology 39(5):e1705848 DOI 10.1080/02724634.2019.1705848. although more complete remains have recently been discovered.

Myacyon
''Myacyon'' is an extinct genus of large sized carnivoran mammals, belonging to the family Amphicyonidae (“bear dogs”), that lived in Africa during the Miocene epoch. Due to the limited scope and fragmentary nature of the severely damaged holotype, as well as the illustrations in its descriptions, which have been called inadequate, usage of this genus poses serious issues. However, it is notable for being one of the last surviving members of its family and its adaptions to hypercarnivory. Its relationships to other amphicyonids are obscure, and it is not closely related to '' Bonisicyon'', the other late surviving African genus, although it has been proposed that it descends from a species of ''Cynelos''. History and species The genus was erected in 1992 on the basis of a severely damaged and fragmented distal half of a right mandible containing m1-m2, and a not yet erupted m3, found at the locality Oued Mya in Algeria. In 2005, the species ''Agnotherium kiptalami'' was desc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Amphicyonidae
Amphicyonidae is an extinct family of terrestrial carnivorans belonging to the suborder Caniformia. They first appeared in North America in the middle Eocene (around 45 mya), spread to Europe by the late Eocene (35 mya), and appear in Asia, and Africa by the early Miocene (23 mya). They had largely disappeared worldwide by the late Miocene (8 mya), with the latest recorded species at the end of the Miocene in Pakistan. They were among the first carnivorans to evolve large body size. Later in their history, they came into competition with hesperocyonine and borophagine canids. As dogs evolved similar body sizes and cranial and dental adaptations, the rise of these groups may have led to their extinction. Amphicyonids are often colloquially referred to as "bear-dogs". Taxonomy The family was erected by Haeckel (1886) lso attributed to Trouessart (1885) Their exact position has long been disputed. Some early paleontologists defined them as members of the family Canidae, but ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ammitocyon
''Ammitocyon'' is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae ("bear dogs"), that lived during the Late Miocene in what is now Spain. It is notable for its extreme adaptations towards hypercarnivory, its extremely robust skeleton, and was one of the last surviving members of its family. History and naming ''Ammitocyon'' was described in the year 2021 by Morales et al. based on comparatively complete remains, originally classified as belonging to '' Thaumastocyon'', enabling a greater understanding of the subfamily Thaumastocyoninae, hitherto only known from fragmentary material. Holotype is the pair of hemimandibles BAT-3'09.1239 and BAT-3'08.604, which belong to the same individual. BAT-3'10.1689 (a skull with strong signs of corrosion, especially in the dorsal region, belonging to a senile individual) and BAT-3'11.453 (a complete mandible belonging to the same individual), as well as the isolated left m2 BAT-3'09.1124, have been designated as par ...

Rhineland-Palatinate
Rhineland-Palatinate ( , ; german: link=no, Rheinland-Pfalz ; lb, Rheinland-Pfalz ; pfl, Rhoilond-Palz) is a western state of Germany. It covers and has about 4.05 million residents. It is the ninth largest and sixth most populous of the sixteen states. Mainz is the capital and largest city. Other cities are Ludwigshafen am Rhein, Koblenz, Trier, Kaiserslautern, Worms and Neuwied. It is bordered by North Rhine-Westphalia, Saarland, Baden-Württemberg and Hesse and by the countries France, Luxembourg and Belgium. Rhineland-Palatinate was established in 1946 after World War II, from parts of the former states of Prussia (part of its Rhineland and Nassau provinces), Hesse (Rhenish Hesse) and Bavaria (its former outlying Palatinate kreis or district), by the French military administration in Allied-occupied Germany. Rhineland-Palatinate became part of the Federal Republic of Germany in 1949 and shared the country's only border with the Saar Protectorate until the latter wa ...

Panthera
''Panthera'' is a genus within the family (biology), family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (''P. tigris''), lion (''P. leo''), jaguar (''P. onca''), and leopard (''P. pardus'') on the basis of common Cranial bones, cranial features. Results of genetic analysis indicate that the snow leopard (formerly ''Uncia uncia'') also belongs to the genus ''Panthera'' (''P. uncia''), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, jaguar and leopard are the only cat species with anatomical structures that enable them to Roar (utterance), roar; the snow leopard cannot. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other Morphology (biology), morphological features, especiall ...

Triceps
The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of 3 parts: the medial, lateral, and long head. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm). Structure The long head arises from the infraglenoid tubercle of the scapula. It extends distally anterior to the teres minor and posterior to the teres major. The medial head arises proximally in the humerus, just inferior to the groove of the radial nerve; from the dorsal (back) surface of the humerus; from the medial intermuscular septum; and its distal part also arises from the lateral intermuscular septum. The medial head is mostly covered by the lateral and long heads, and is only visible distally on the humerus. The lateral head arises from the dorsal surface of the humerus, lateral and proximal to the groove of the radial nerve, from the greater tubercle down to ...

Ischyrocyon
''Ischyrocyon'' is an extinct genus of bear dogs, of the subfamily Amphicyoninae, which inhabited North America during the Late Miocene. It lived ~13.6—10.3 Ma ago, existing for approximately . Behavior In a study published in 2020, examination of the relative grinding area of the molars of ''Ischyrocyon'' indicated that it was purely carnivorous, and not omnivorous as previously assumed. Both ''Ischyrocyon'' and its relative, ''Amphicyon'' possessed skeletal features that are characteristic of both ambush and pursuit living predators. As such, it is believed via this evidence that ''Ischyrocyon'' probably pursued prey for longer distances but at slower speeds than living ambush predators do. Upon catching up to its prey, ''Ischyrocyon'' probably grabbed its victims using its powerfully muscled forelimbs before killing them by tearing into the prey's ribcage or neck using its large, strong canines set in its narrow snout.

Amphicyon
''Amphicyon'' ("ambiguous dog") is an extinct genus of large carnivorous bone-crushing mammals, popularly known as bear dogs, of the family Amphicyonidae, subfamily Amphicyoninae, from the Burdigalian Epoch until the late Pliocene, with the creature having bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa from 16.9 to 2.6 Ma ago, existing for approximately . Morphology ''Amphicyon'' was the typical bear-dog amphicyonid with morphology similar to both bears and dogs. With its robust build and maximum length of 2.5 m (8 ft), the largest species looked more like a bear than a dog. It had a large heavy tail, thick neck, robust limbs and teeth like a wolf. It was probably an omnivore with a lifestyle comparable to that of the brown bear. The ''Amphicyon'' was very large for predators of its time but this advantage eventually became a disadvantage because its large body mass was too large to take faster prey. ''A. major'' has been est ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
