By the Ordovician time period, approximately 460 million years ago, trilobite eyes had developed into an almost dizzying array of sizes and shapes. Some, like those attached to species such as Asaphus kowalewski (pictured) and Cybele panderi, sat atop spindly “stalks” up to three inches long. This feature presumably allowed the trilobite a better view of the world around it, even when it may have been lurking under a thick layer of silt or mud along the sea bottom. Other trilobites of the time period, such as the aptly named Cyclopyge bohemica, developed huge wrap-around holochroal eyes featuring over a thousand small, tightly packed lenses that allowed a virtually uninterrupted view of the ocean surrounding it.
When gathering morels, care must be taken to distinguish them from the poisonous false morels, including Gyromitra esculenta, Verpa bohemica, and others. When in doubt identifying a mushroom, err on the side of caution and do not consume! #PSA#FungiFacts #FantasticFungi #Mushrooms #Fungiculture
