## thagomizer_title.jpg

The image shows a fossilized tail of a stegosaurus dinosaur. The tail is composed of multiple vertebrae, each with prominent spikes protruding from its top and bottom edges. These spikes are long and sharp, suggesting they were likely used for defense against predators.

The background appears to be a plain surface, possibly a table or floor, which helps in focusing attention on the fossilized tail itself. The text at the bottom of the image provides information about this specimen:

"The 'thagomizer' is the name for the spiked tail of a stegosaurus dinosaur. It didn't have an official name until the cartoonist Gary Larson did a comic about it, named it, and the scientific community just accepted it and started using it too."

The text also includes a credit line at the top right corner: "Image credit: Wikimedia."
