The images you’ve shared showcase trilobites, an extinct group of marine arthropods that lived during the Paleozoic Era, around 521 to 252 million years ago. Here’s a little about what you’re seeing:

Top Image:

• This is a highly detailed trilobite fossil reconstruction, likely enhanced or digitally modeled to show what the living creature might have looked like.

• You can see the long spiny protrusions (often used for defense or sensing the environment), and segmented body parts that helped them move along the sea floor.

🪨 Bottom Left & Right Images:

• These are actual trilobite fossils embedded in rock.

• The fossils clearly show the segmented exoskeleton and ridged thorax, which are classic features of trilobites.

• The bottom right image features multiple specimens preserved together, indicating a possible group movement or a mass mortality event.
