T-Rex: Diatoms are a group of microalgae found in waters all over the world. And they make more than 20% of the oxygen on the planet!
T-Rex: Thanks, diatoms!
T-Rex: And they have SILICA-based shells, which don't decay very quickly and which don't occur naturally in our bodies!
Dromiceiomimus: Wow, algae science is kinda interesting I GUESS, but can this be used to help me get away with murder?
T-Rex: Dromiceiomimus!
T-Rex: It absolutely can!!
Utahraptor: You can sometimes find diatoms even in heavily decayed bodies, yeah?
T-Rex: Exactly!
T-Rex: So if you murder someone and want it to LOOK like drowning, throwing them in a lake won't be enough. You gotta get some diatoms in them lungs!
Utahraptor: Ah, but forensics can test if the lung diatoms match those in the surrounding water.
T-Rex: Huh! Well, this is way more work than I was expecting so I've decided to simply not murder anyone.
Off panel: Same!
T-Rex: 〚thinks〛 WAIT.
T-Rex: 〚thinks〛 That's exactly what a MURDERER would say??
