The Bigger They Are: 10 Ice Age Giants

August 12, 2008
Original image

The Pleistocene Era began 1.8 million years ago and ended roughly 10,000 years ago. During that period were several Ice Ages. Many giant sized animals and birds that seem familiar to us (because they resemble modern animals) roamed the earth. They became extinct, possibly due to environmental conditions or disease, or possibly because they were hunted by humans.

Irish Elk

The Irish Elk (Megaloceros) is the largest deer species ever, although it was not an elk, nor was it exclusively Irish. Megaloceros ranged across Europe, Asia, and northern Africa. The biggest specimens are seven feet tall at the shoulder and have antlers that span 12 feet! It became known as the Irish Elk because the Irish would find remains in peat bogs and display the antlers in hunting lodges as if they bagged the beast themselves. Because of its wide geographic range, it is not known when the last of these deer died out.

Giant Short-Faced Bear

432bear.jpg

The Giant Short-Faced Bear (Arctodus simus) had the ability to run on his two long hind legs, and may have reached a running speed of 40 miles per hour! It would have been a frightening sight, as this bear stood five feet tall on four legs, but rose to 12 feet when standing up. It lived in the western US, Canada, and Alaska.

Syrian Camel

432Camel.jpg

The fossil bones of giant Syrian Camel was only discovered two years ago in central Syria. The 12-feet-tall at the shoulder bones are around 100,000 years old. Previously, scientists thought camels had only existed in the Middle East for about 10,000 years.

Giant Sloths

432Megatherium.jpg

The Giant Ground Sloth (Megatherium americanum) weighed five tons and stood 12 feet tall on its hind legs! Native to South America, it ate tree leaves like its descendants, the modern sloths, but was way too heavy to climb. There were several other species of large ground sloths that inhabited North America, none as large as Megatherium. Although giant sloths died out 10,000 years ago, the last species of ground sloths may have survived until 1550 AD in the Caribbean.

Saber Toothed Tiger

432smilodon.jpg

There were several species of Saber Toothed Tiger (Smilodon) in both North and South America during the Ice Age. The largest, Smilodon populator lived in Brazil and had canine teeth up to seven inches long. It probably weighed about 800 pounds, the size of a modern lion. Saber toothed cats are believed to have co-existed with humans for about a thousand years, and may have been hunted to extinction.

North American Lion

432PantheraLeoAtrox1.jpg

The North American Lion (Panthera leo atrox) was bigger than the Smilodon species, but hasn't gotten as much press because there are not as many fossil specimens, or maybe because they had proportionally normal sized teeth for a big cat. They were still big teeth, since the largest lions were over eight feet long! (Image: Dantheman9758)

Giant Beaver

432beaver.jpg

The Giant Beaver (Castoroides ohioensis) wins the prize for the largest rodent, at least in North America. Skeletal remains have been found indicating the animal was about nine feet long. Although they didn't have the characteristic flat tail of the modern beaver, they resembled their modern cousins otherwise.

Teratorn

432teratorn.jpg

Giant Pleistocene species weren't limited to mammals. The Teratorn (Argentavis magnificens) was an ancestor of the Giant Condor with a wingspan of 19 to 28 feet! With wings folded, it stood as tall as a man and could weigh over 200 pounds. Found in Argentina, it was the largest flying bird ever known.

Mastodon

432Mastodon.jpg

Mastodons (Mammut americanum) were not mammoths, although both were hairy, resemble elephants, and roamed North America until ten thousand years ago. Mastodons ate from trees, while mammoths grazed on the ground. Mastodons are somewhat shorter and stockier than mammoths, reaching about ten feet tall. They weren't any larger than elephants that exist today, but they were pretty big animals anyway.

Mammoth

432Woolly_mammoth.jpg

The Wooly Mammoth (Mammuthus primigenius) belonged to the same family as modern elephants, and were about the same size. They lived in Europe, Asia, and North America ranging up to the Arctic. Woolly Mammoths in the northernmost areas had hair up to three feet long, and curly tusks up to five feet long. Mammoth survived longer than other Ice Age giants, with the biggest extinction occurring about 8,000 years ago. A dwarf species survived on Wrangel Island near Siberia until about 1700 BC.

The dinosaurs got really big, and they died out. Pleistocene mammals grew very big, and they died out. It makes you wonder... where will the human obesity epidemic lead us?

When the FBI Went After Mad Magazine
April 29, 2017
Original image
Warner Bros., IStock

In a memo dated November 30, 1957, an agent with the Federal Bureau of Investigation identified as “A. Jones” raised an issue of critical importance: "Several complaints to the Bureau have been made concerning the 'Mad' comic book [sic], which at one time presented the horror of war to readers."

Attached to the document were pages taken from a recent issue of Mad that featured a tongue-in-cheek game about draft dodging. Players who earned such status were advised to write to FBI Director J. Edgar Hoover and request a membership card certifying themselves as a “full-fledged draft dodger.” At least three readers, the agent reported, did exactly that.

Mad, of course, was the wildly popular satirical magazine that was reaching upwards of a million readers every other month. Published by William Gaines, who had already gotten into some trouble with Congress when he was called to testify about his gruesome horror comics in 1954, Mad lampooned everyone and everything. But in name-checking the notoriously humorless Hoover, Gaines had invited the wrong kind of attention.

The memo got several facts incorrect: Mad had switched from a comic book to a magazine format in 1955, and it was Gaines’ E.C. Comics that had “presented the horror of war” in other titles. Despite getting these crucial pieces of information wrong, Jones didn’t hesitate to editorialize: "It is also of interest to note that…it is rather unfunny.”

The agent recommended the Bureau’s New York offices “make contact” with Mad’s headquarters to “advise them of our displeasure” and to make sure “that there be no repetition of such misuse of the Director’s name.”

Less than a week later, the Feds entered the hallowed hallways patrolled by Alfred E. Neuman. Their New York office would later report to Hoover directly that they had met with John Putnam, the magazine’s art director. (Conveniently, Gaines was not in that day.) Putnam told the agents he regretted the magazine using Hoover’s name and that nothing malicious was intended:

Putnam said that the use of the membership card and the name and address of the Director at the end of the game was referred to in their business as a 'gag' or 'kicker' in the same way that a comedian like Bob Hope or Milton Berle might use it.

Putnam swore that Mad would never again take Hoover’s name in vain; Gaines sent off a letter of sincere apology to the Director.

The Smoking Gun

Just two years later, in January 1960, Agent A. Jones was forced to file a second notice about the shenanigans at Mad. A recent issue had made not one, but two derogatory mentions of Hoover, including one in which he is blatantly and disrespectfully portrayed as being associated with a vacuum cleaner, “The Honorable J. Edgar Electrolux”:  

Obviously, Gaines was insincere in this promise…and has again placed the Director in a position of ridicule…it is felt we should contact Gaines…and firmly and severely admonish them concerning our displeasure…

It was by now clear Mad was not only polluting young minds, but that Gaines had absolutely no regard for the honorable Hoover’s position.

In June 1961, the FBI’s worst fears had been realized. Detailing an investigation into a Seattle-area extortion attempt led to the following:

Investigation … resulted in gaining admissions from the victim’s 12-year-old son and an 11-year-old companion that they had gotten the idea of preparing an extortion letter after reading the June issue of 'Mad' magazine.   

Working in concert with the Buffalo field office, the FBI determined another letter had been sent by a young boy demanding money in the style of a recent issue’s extortion advice. And there was a third under review that was sent to the agent of some professional wrestlers.

Mad was quickly becoming the scourge of the federal government. The FBI suggested the magazine be brought to the attention of the Attorney General for “instructing [readers] to deliberately violate the Federal Law.” They tried reaching out to Gaines, who was on vacation. (Time and again, Gaines simply not being in the office when called upon seemed to confound the FBI.)

Agent A. Jones, having exhausted all attempts to reason with these irresponsible anarchists, filed one last memo:

Despite assurances, they have continued to publish slurring remarks about the Bureau. In view of this situation, it was deemed useless to protest all such irresponsible remarks to a magazine of this poor judgment and capriciousness … we will have to wait and see if our action will result in increased discretion by this publication.

Poor A. Jones was unable to put an end to Mad’s reign of terror. But the magazine redeemed itself somewhat. In the 1970s, when the Bureau was trying to suppress the influence of the Ku Klux Klan, an agent suggested they copy and distribute a sticker from the magazine that read, “Support Mental Illness—Join the Klan!”

Hoover said no.
