Wow in the World: How the Dinosaurs Got So Big – An Investigation in Fossilized Feces

Episode Release Date: March 31, 2025
Hosts: Mindy Thomas and Guy Raz

Introduction

In this captivating episode of Wow in the World, hosts Mindy Thomas and Guy Raz delve into a fascinating scientific mystery: how dinosaurs evolved from small, cat-sized creatures into the gigantic reptiles that once dominated the Earth. This investigative journey centers around an unconventional yet pivotal source of information—fossilized dinosaur feces, known scientifically as coprolites and bromelites.

The Big Assignment

The episode kicks off with Mindy Thomas being tasked by her editor, Guy Raz, to write the weekly feature article for the Bonkerball's Bugle newspaper. While initially slated to cover a light-hearted topic—"Why Six is Afraid of Seven"—Mindy uncovers a more significant story that promises to make headlines.

Mindy Thomas [03:13]:
"I have an idea."

She reveals her plan to investigate the mysterious growth patterns of dinosaurs, proposing an in-depth report titled "The Mystery of How the Dinosaurs Came to Rule the World."

Unveiling the Mystery at the National Archive

Determined to uncover the truth, Mindy and Guy, accompanied by their intern Dennis, visit the National Archive of Coprolites and Bromelites. Here, they meet Professor Felicity Guano, a leading expert in paleontology.

Mindy Thomas [05:07]:
"I have a better idea for this week's feature article."

The team is introduced to a vast collection of fossilized dinosaur feces, which are crucial for understanding the dietary habits and, consequently, the evolutionary pathways of these ancient creatures.

Professor Felicity Guano [12:06]:
"If you're able to understand what's inside these bromelites, then you can also figure out what sorts of foods these dinosaurs were eating back then."

Analyzing the Dino Diets

Using a micro CT scanner, Professor Guano demonstrates how the team can examine the contents of these fossils without damaging them. This technology allows for a non-invasive peek into the ancient diets of dinosaurs.

Professor Felicity Guano [16:15]:
"No, it scans the specimen and shows us images of the inside without needing to break it."

As they analyze various coprolites, the team discovers remnants of specific plants that began to emerge during the period when dinosaurs started to grow significantly in size.

Mindy Thomas [18:13]:
"What if there was a bunch of new plants that popped up around this time that only dinosaurs could eat?"

This revelation suggests that the introduction of these new plants, thriving in volcanic-rich soils, provided essential nutrients that enabled certain dinosaur species to expand rapidly in size and dominate their ecosystems.

Guy Raz [18:46]:
"And volcanic soil is great for growing plants."

The Breakthrough

The investigation leads to a groundbreaking conclusion: the availability of new plant species, accessible only to specific dinosaurs, was a key factor in their massive growth. These plants likely offered superior nutrition, supporting the rapid expansion and dominance of these reptiles.

Professor Felicity Guano [19:07]:
"Yes, precisely."

This insight not only solves the mystery of dinosaur gigantism but also highlights the intricate relationship between flora and fauna in prehistoric times.

Wrapping Up the Investigation

With their findings in hand, Mindy and Guy rush back to the Bonkerball's Bugle headquarters to draft their monumental story. Although their article doesn't clinch a Pulitzer, the investigation marks a significant achievement in their journalistic careers and contributes valuable knowledge to the field of paleontology.

Mindy Thomas [19:50]:
"It didn't win the Pulitzer that year. That went to some tabloid piece on cubic wombat. But I'll never forget Professor Guano and my first big break as an investigative reporter at the Bonker Balls Bugle."
