Thought it would be three thundereggs!?!?

Based on the visual characteristics of the rock in the image, it appears to be an iron-rich sedimentary rock, possibly an ironstone or banded iron formation (BIF). Here are some key observations:

Color: The rock has a reddish-brown hue, which is typical of iron oxides like hematite (Fe₂O₃) or goethite (FeO(OH)).
Texture: The rock shows a layered or banded structure with a mix of different shades of red, brown, and some lighter minerals, which suggests it might be a sedimentary rock formed in layers over time.
Luster: The wet appearance gives it a glossy look, which can sometimes help in identifying minerals by enhancing their color and luster.
Composition: The presence of small white or light-colored inclusions could be quartz, calcite, or other minerals commonly found in iron-rich sedimentary environments.

Ironstones are often formed in ancient marine or lake environments where iron was precipitated out of the water and deposited in layers. Banded iron formations are particularly notable for their distinct layers of iron oxides and silica, formed under specific chemical conditions in the Earth's early history.
