Titanoboa cerrejonensis

Overview

Titanoboa was the largest snake that ever lived—a massive constrictor that slithered through the swamps of South America approximately 60-58 million years ago during the Paleocene epoch. This monster could grow longer than a school bus and weigh as much as a small car!

Taxonomy & Classification

• Class: Reptilia
• Family: Boidae (related to modern boas)
• Diet: Carnivorous
• Type: Giant constrictor snake

Titanoboa was related to today's boas and anacondas, but MUCH bigger!

Physical Characteristics

Mind-Blowing Size

• Length: 12.8-14 meters (42-46 feet)!
• Weight: 750-1,100 kg (1,650-2,500 lbs)
• Diameter: Over 1 meter (3 feet) at the thickest point
• Comparison: Longer than a T. rex!

Massive Proportions

• Thicker than an oil drum at its widest
• Could easily coil around a crocodile and crush it
• Vertebrae (backbones) the size of dinner plates
• Skull could swallow prey the size of a cow!

Size Comparison

Snake	Maximum Length	Maximum Weight
Titanoboa	14m (46 ft)	1,100 kg
Green Anaconda	5.2m (17 ft)	227 kg
Reticulated Python	7.5m (25 ft)	135 kg
King Cobra	5.5m (18 ft)	12 kg

Titanoboa was twice as long and five times heavier than modern anacondas!

How Did It Get So Big?

The Climate Connection

Titanoboa's size tells us about its world:

• Snakes are cold-blooded—their size depends on temperature
• The hotter the climate, the bigger snakes can grow
• Titanoboa's existence proves Earth was much warmer then
• Average temperatures were probably 30-34°C (86-93°F)
• Like a global tropical greenhouse!

Hunting & Diet

Apex Predator

Titanoboa was the top predator of its ecosystem:

• Ate giant crocodilians (some over 6 meters long!)
• Hunted large fish
• Possibly ate early mammals
• Used constriction to kill prey (squeezing until death)
• Could swallow prey much larger than its head

Hunting Style

• Probably an ambush predator
• Waited in murky swamp water
• Struck with lightning speed
• Coiled around prey and squeezed
• Swallowed prey whole—took weeks to digest!

---

Habitat

Tropical Swamp World

Titanoboa lived in:

• Steamy tropical rainforests
• Swamps and river systems
• Coal swamp forests (like Louisiana bayous but hotter)
• What is now Colombia, South America

Post-Dinosaur World

• Lived 5-10 million years after dinosaur extinction
• Dinosaurs were gone—giant reptiles filled the gap!
• No large predatory mammals yet
• Titanoboa was the undisputed king

Discovery

Found in a Coal Mine!

• Discovered in 2009 in the Cerrejón coal mine, Colombia
• Found along with giant turtles and crocodilians
• Vertebrae were so big, scientists initially couldn't believe it
• Over 28 individual snakes identified!
• Named by scientists Jonathan Bloch and Carlos Jaramillo

---

Modern Relative: The Anaconda

Titanoboa and anacondas had similar lifestyles:

• Both lived in swamps and rivers
• Both ambush predators
• Both excellent swimmers
• But Titanoboa was much, MUCH bigger!

---

Why Did It Go Extinct?

Climate Change

• Earth cooled down over millions of years
• Colder temperatures couldn't support such large snakes
• Smaller snakes became more successful
• Giant reptiles gave way to rising mammals

---

Pop Culture

On Screen

• Featured in Smithsonian documentary "Titanoboa: Monster Snake"
• Appeared in various video games and TV shows
• A life-size model toured museums worldwide
• Captures imagination as the ultimate snake nightmare!

---

Cool Facts

• Titanoboa could eat a crocodile for lunch!
• Its discovery helped scientists understand ancient climates
• A Titanoboa backbone is larger than your head
• It lived in the same area where massive coal deposits formed
• Scientists first thought the giant vertebrae were from a whale!
• The Cerrejón mine where it was found is one of the largest open-pit coal mines in the world
• Titanoboa proves that climate controls animal size
• If one existed today, it could easily eat a human!

Titanoboa reminds us that the age of giant reptiles didn't end with the dinosaurs—for millions of years afterward, monstrous snakes ruled the tropical swamps!
