* Ursus, Son of Hercules ( Ursus ) 1961, starring Ed Fury ( a. k. a. Mighty Ursus in England )

* Son of Hercules in the Land of Fire ( Ursus In The Land Of Fire ) 1963, starring Ed Fury

Ursus was referred to as a " Son of Hercules " in two of the films when they were dubbed in English ( in an attempt to cash in on the then-popular Hercules craze ), although in the original Italian films, the Ursus character had no connection to Hercules whatsoever.

* Ursus, Son of Hercules ( released in Italy as Ursus ) 1961, starring Ed Fury ( a. k. a. Mighty Ursus in England )

* Son of Hercules in the Land of Fire ( released in Italy as Ursus In The Land Of Fire ) 1963, starring Ed Fury

This film was released in the United States initially as Mighty Ursus and was later adapted for the American television film package, The Sons of Hercules, where it was retitled " Ursus, Son of Hercules ".

* Ursus nella terra di fuoco / Ursus in the Land of Fire ( 1963 ) aka Son of Hercules in the Land of Fire ( 1963 )

Other films starred such heroes as Ursus, Samson, Hercules and Goliath.

Although two of them did originally feature Hercules ( and not his sons ), four of the films were originally Maciste movies in Italy, two of them were originally Ursus movies, and the other six were just isolated gladiator or mythological hero movies that the American distributors didn't feel deserved a full-blown theatrical release in the USA.

Most pepla featured a supernaturally strong muscleman as the protagonist, such as Hercules, Samson, Goliath, Ursus or Italy's own popular folk hero Maciste.

The movies were made into a series of sorts by splicing on the same opening and closing theme song and newly-designed voice-over narration that desperately attempted to link the protagonist of each film to the Hercules mythos, since few American viewers had a familiarity with Italian film heroes such as Maciste or Ursus.

* Hercules, Prisoner of Evil was originally an Ursus film in Italy.

In the English-dubbed version of one Ursus film ( retitled Hercules, Prisoner of Evil ), Ursus was actually referred to throughout the entire film as Hercules.

The character Ursus was featured in a number of Italian adventure films from 1961 to 1964.

* Ursus ( film ), 1961 Italian film

The brown bear ( Ursus arctos ) is a large bear distributed across much of northern Eurasia and North America.

The scientific name of the brown bear, Ursus arctos, can be considered a tautology, since " Ursus " means " bear " in Latin and " arctos " comes from the Greek word for bear.

Brown bears are thought to have evolved from Ursus etruscus.

Carnivorans are the most diverse in size of any mammalian order, ranging from the least weasel ( Mustela nivalis ), at as little as and, to the polar bear ( Ursus maritimus ), which can weigh up to, to the southern elephant seal ( Mirounga leonina ), whose adult males weigh up to and measure up to in length.

He also sought the opinions of many of the astronomers to whom he had sent Mysterium, among them Reimarus Ursus ( Nicolaus Reimers Bär )— the imperial mathematician to Rudolph II and a bitter rival of Tycho Brahe.

Ursus did not reply directly, but republished Kepler's flattering letter to pursue his priority dispute over ( what is now called ) the Tychonic system with Tycho.

Through most of 1601, he was supported directly by Tycho, who assigned him to analyzing planetary observations and writing a tract against Tycho's ( by then deceased ) rival, Ursus.

The black bear native to New Mexico, Ursus americanus amblyceps, was formally adopted as the state's official animal in 1953.

The polar bear ( Ursus maritimus ) is a bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses.

He chose the scientific name Ursus maritimus, the Latin for ' maritime bear ', due to the animal's native habitat.

However, evidence of hybrids between polar bears and brown bears, and of the recent evolutionary divergence of the two species, does not support the establishment of this separate genus, and the accepted scientific name is now therefore Ursus maritimus, as Phipps originally proposed.

The mitochondrial DNA ( mtDNA ) of the polar bear diverged from the brown bear, Ursus arctos, roughly 150, 000 years ago.

When the polar bear was originally documented, two subspecies were identified: Ursus maritimus maritimus by Constantine J. Phipps in 1774, and Ursus maritimus marinus by Peter Simon Pallas in 1776.

Ursus maritimus tyrannus — descended from Ursus arctos — became extinct during the Pleistocene.

Ursus, would become the first of 117 " doges " ( doge is the Venetian dialect development of the Latin dux (" leader "); the corresponding word in English is duke, in standard Italian duce.

) Whatever his original views, Ursus supported Emperor Leo's successful military expedition to recover Ravenna, sending both men and ships.
