Titanoboa

Titanoboa Description & Size

If you think the 15-foot-long anaconda is a horror show, imagine titanoboa, a 42-foot-long boa constrictor that was 3 feet wide at its widest point. There are some who even believe this snake could grow to 50 feet in length.

Not only that, it could weigh as much as 2,500 pounds which is well over a ton. Indeed, it was the largest predator on earth during the middle to the latter part of the Paleocene epoch. Titanoboa came after the meat-eating dinosaurs went extinct 65 million years ago and before the arrival of the megalodon, a monstrous, 33.5-foot-long shark whose very name means “big tooth.”

Paleontologists also believe that Titanoboa had brownish or grayish skin, which camouflaged it, at least somewhat, in the muddy rivers of the tropical rainforests where it flourished. How fast it moved on land and whether or not it could climb trees is debatable.

Though scientists have only found some sections of the snake’s backbone and pieces of its skull, it was enough to let them calculate the fantastic size of this snake and discover that it was a snake in the first place. They could even tell that it was related to modern boas and anacondas and placed it in the still extant Boidae family.

Origin of Its Name

Titanoboa gets its name from the Titans, great old gods from Greek mythology. Boa comes from the Latin name for a large serpent from Pliny the Elder’s Natural History. Cerrejonensis means “, “Cerrejón” because the first fossils were found in the Cerrejón coal mine in La Guajira, Colombia. There do not appear to be any subspecies of T. cerrejonensis.

Diet – What Did the Titanoboa Eat?

One would think that a snake the size of Titanoboa could eat anything it fancied, but scientists believe that the snake ate mostly fish. They came to this conclusion because of the snake’s palate and the number and anatomy of its teeth.

The fish were most likely types of lungfish or types of bony fish called osteoglossomorphs. Most of these fish are now extinct. When it wasn’t eating fish, Titanoboa probably ate other reptiles, crocodilians, and birds. A grown Titanoboa could quite easily vanquish a 300-pound turtle.

Habitat – When and Where It lived

Titanoboa lived in the hot tropical rainforests that flourished between 58 and 60 million years ago, well after all the carnivorous predatory dinosaurs such as Tyrannosaurus rex were safely dead. Because it was so large and heavy, the snake probably spent most of its life in the many rivers of its habitat.

As with a large shark or whale, the water would have kept its 2-ton body buoyant. It’s possible that the snake could hold its breath underwater for as long as an hour.

Threats And Predators

Titanoboa was the apex predator not just of South America but basically of the entire planet. Paleontologists have not yet found any animal that would have dared to prey on a grown Titanoboa. Indeed, some scientists believe the snake gladly swallowed whole crocodilians along with fish.

However, it is possible that baby titanoboas and Titanoboa eggs were preyed upon by the same crocodilians the adults ate. The one threat to the species as a whole was climate change. In this case, the climate started to cool which bode ill for Titanoboa.

Discoveries and Fossils – Where It was Found

The first Titanoboa fossils were discovered quite recently. The fossils of 30 of the snakes were discovered in 2009 in the Cerrejón coal mines by paleontologist Jonathan Bloch and his colleagues. The team discovered the fossils in rocks that dated back 58 million years.

They not only discovered the bones of this snake but evidence that it lived in a primeval rainforest. Now, fossilized vertebrae of the snake can be found in the Geological Museum José Royo y Gómez in Bogota, Colombia.

Extinction – When Did It Die Out?

Titanoboa died out around 58 to 60 million years ago, so its dominance was fairly brief in geological terms. Scientists aren’t quite sure, but they believe that climate change had something to do with it. The climate started to cool, and the enormous snake and other large reptiles couldn’t maintain their metabolism.

Also, the rainforests where Titanoboa reigned gave way to grassland over time. All of this paved the way for the emergence and eventual dominance of smaller reptiles.

Similar Animals to the Titanoboa

Some of the animals similar to the Titanoboa are:

• Gigantophis garstini. This snake lived during the Eocene epoch around 40 million years ago in what is now Algeria and Egypt. It was only 30.5 to 35.1 feet long and is described from only a few bits of vertebrae.
• Eoconstrictor. These snakes also lived during the Eocene, but in Germany. The type species is E. fischeri. Eoconstrictor snakes were believed to have an infrared vision.
• Boavus. This is another extinct genus of boas. They also lived in the Eocene and were found in the western United States.
• Palaeophis. These Eocene epoch snakes could grow between 29.5 to 40.4 feet, which makes them rivals of the earlier Titanoboa in terms of length. They were aquatic snakes found in North America, Europe, and northern Africa.
