That Was One Big Shark

Shark Tooth (Carcharodon megalodon) from the Miocene (25 million years ago) of the Hawthorne Formation, South Carolina, USA.
You know with a big tooth like that a lot of people are going to write a lot of words talking about it. I have added some additional information from wiki. I did try to only add important info and I left a whole lot out. If you want more take a look at the Wikipedia article. There is enough in this to keep you busy for a while.
Information from wiki
Megalodon, meaning “big tooth”, is an extinct species of shark that lived approximately 15.9 to 2.6 million years ago, during the Cenozoic Era (middle Miocene to end of Pliocene).
Regarded as one of the largest and most powerful predators in vertebrate history, C. megalodon probably had a profound impact on the structure of marine communities. Fossil remains suggest that this giant shark reached a length of 18 metres (59 ft), and also indicate that it had a cosmopolitan distribution. Scientists suggest that C. megalodon looked like a stockier version of the great white shark.
C. megalodon had a cosmopolitan distribution; its fossils have been excavated from many parts of the world, including Europe, Africa and both North and South America, as well as Puerto Rico, Cuba, Jamaica, the Canary Islands, Australia, New Zealand, Japan, Malta, the Grenadines and India. Megalodon teeth have been excavated from regions far away from continental lands, such as the Mariana Trench in the Pacific Ocean.
The most common megalodon fossils are its teeth. Diagnostic characteristics include: triangular shape, robust structure, large size, fine serrations, and visible V-shaped neck. Megalodon teeth can measure over 180 millimetres (7.1 in) in slant height or diagonal length, and are the largest of any known shark species
Due to fragmentary remains, estimating the size of C. megalodon has been challenging. However, the scientific community has concluded that C. megalodon was larger than the whale shark, Rhincodon typus. Scientists focused on two aspects of size: total length and body mass.
A team of Japanese scientists, T. Uyeno, O. Sakamoto, and H. Sekine, discovered and excavated partial remains of a megalodon, with its nearly complete associated set of teeth, from Saitama, Japan, in 1989. Another nearly complete associated megalodon dentition was excavated from the Yorktown Formations of Lee Creek, North Carolina, in the United States and served as the basis of a jaw reconstruction of C. megalodon at the American Museum of Natural History in New York City. These associated tooth sets solved the mystery of how many teeth would be in each row of the jaws of the megalodon. As a result, highly accurate jaw reconstructions became possible. More associated megalodon dentitions were found in later years. Based on these discoveries, scientists S. Applegate and L. Espinosa published an artificial dental formula (representation of dentition of an animal with respect to types of teeth and their arrangement within the animal’s jaw) for megalodon in 1996. Most accurate modern C. megalodon jaw reconstructions are based on this dental formula.
The extraordinary bite forces in C. megalodon must be considered in the context of its great size and of paleontological evidence suggesting that C. megalodon was an active predator of large whales.
Megalodon had enough adaptability to inhabit a wide range of marine environments (i.e., shallow coastal waters, areas of coastal upwelling, swampy coastal lagoons, sandy littorals, and offshore deep water environments), and exhibited a transient lifestyle. Adult megalodon were not abundant in shallow water environments and mostly lurked offshore. C. megalodon may have moved between coastal and oceanic waters, particularly in different stages of its life cycle.
Fossil evidence suggests that the preferred nursery sites of C. megalodon were warm water coastal environments, where threats were minor and food plentiful. Nursery sites were identified in the Gatun Formation of Panama, the Calvert Formation of Maryland, Banco de Concepción in the Canary Islands, and the Bone Valley Formation of Florida. As is the case with most sharks, C. megalodon gave birth to live young. The size of neonate megalodon teeth indicate that megalodon pups were around 2 to 4 metres (6.6 to 13.1 ft) in total length at birth. Their dietary preferences display an ontogenetic shift. Young megalodon commonly preyed on fish, giant sea turtles, dugongs and small cetaceans; mature megalodon moved to off-shore cetacean high-use areas and consumed large cetaceans

Dubai Fireworks Display Goes On Despite Hotel Fire Just A Mile Away - Newsy

Burj Khalifa, World’s Tallest Artificial Structure 

At 828 m (2,717 ft), the Burj Dubai, now alluded to as the Burj Khalifa is the tallest man-made structure on the planet. The astounding building was formally opened in January 2010. Development took 6 years to finish at an expense of around US $1.5 billion.

The Dubai government apparently built up the Burj Dubai extends as a method for broadening from its essential oil based economy in the early years to a travel and tourism based economy all the more as of late. Dubai has absolutely put itself on the world guide with its quick development and its forward vision. Other sensational advancements in Dubai incorporate the Palm Island Dubai and the World Islands Dubai, both of which have helped put Dubai on the worldwide guide.

One of the core bits of the Burj Dubai, found at the base of the structure is a huge water wellspring. With more than 6,600 lights and 50 hued projectors, the wellspring is choreographed to “move” to a consolidate of established, current and Arabic music. The wellspring is an incredible sight as it shoots water more than 150m (490 ft) into the air.

From the time you leave Dubai Mall to begin your adventure towards the Observation Deck, each minute acquaints you with another rising innovation. The plane rate lifts, the discriminatory limitation dividers, remarkable tallness, and general plushness rises above into a virtual feeling of an outsider province, however a man-made one. Star trek was simply a film, yet in the event that there is anything that could come as close actually, it would need to be Burj Khalifa.

The visit on the Observation Deck goes on for up to one hour amid which vacationers are given an opportunity to view Dubai through extraordinary telescopes with close-up continuous perspectives. They could likewise look for a keepsake or two preceding slipping back.

Burj Khalifa is an astounding destination in Downtown Dubai whose living arrangements and office spaces are interested in just a world class few. Instantly, it houses the Armani lodging, the world’s first inn created and planned by Giorgio Armani himself. While the perception deck experience can abandon you feeling overpowered, don’t miss the staggering Burj Khalifa Park and Dubai Fountain exhibitions.

Hawaii's Swelling Lava Lake Charts a Volcano's Hidden Plumbing

Geophysicists used unique seismic signatures to track the cyclic rise and fall of lava inside Hawai'i Volcanoes National Park's Overlook crater.

Over the past 7 years, the “Overlook crater” near the summit of Kilauea Volcano has grown from just 35 to more than 200 meters wide and now hosts one of the largest lava lakes in the world (shown here). Recent research sheds light on gas-pistoning activity that may have contributed to the dramatic rise and fall of lava columns connected to the crater. Credit:USGS

It’s been 7 years since an explosive eruption left a massive hole in Halemaʻumaʻu crater, just below an overlook point at the summit of Kilauea Volcano in Hawaiʻi Volcanoes National Park. As the surrounding walls have collapsed, the “Overlook crater” has grown from just 35 to more than 200 meters wide and now hosts an impressive lava lake. Scientists suspect the lava lake’s depth, estimated at around 200 meters, makes it among the largest in the world.

The action has been monitored by a network of Hawaiian Volcano Observatoryseismometers, which allowed Chouet and Dawson to track tremors originating from a kilometer below the surface. Before the lake formed, the instruments caught degassing bursts from the top of the lava column. Since then, much of the seismic activity can be explained by rockfalls as the crater grows. A third type of activity is more puzzling, consisting of unusual pressure drops from somewhere within the magma system, but with no signs of disturbance on the lake’s surface.

The authors focused their efforts on a fourth type of activity known as gas pistoning, in which the lava column sees a cyclic approximately 20-minute-long rise and fall of its thinly crusted surface. During one such period, recorded in high detail over 5 days in the summer of 2011, the lava column swelled by tens of meters and featured hundreds of gas piston events. Geologists say the activity is caused by the accumulation of gas in a layer of foam at the top of the column before it’s released—often forcefully when the foam collapses.

The pair tracked the signature to a single point source that sits 1 kilometer belowHalemaʻumaʻu crater’s eastern flank. The seismic waves also map out the volcano’splumbing system, which consists of pipes, dikes, and fissures beneath the park that correspond well to previous attempts to chart the underground network.

Using numerical simulations, the researchers calculated that layers of foam—perhaps tens of meters high—grew and collapsed over the 5-day period and that the gas-pistoning activity likely happened in a 6-meter-wide pipe that connected the crater to an adjacent dike system. This study is central to determining the behavior of the magmatic system beneath Halemaʻumaʻu and volcanic systems in general, protecting communities in Hawaii and around the world.
