Pygites brachiopods… or bizarre fossil scrotal phylogeny?

Caption: “Pygites is unusual for a Terebratulid brachiopod. It shares many of the same features that other brachiopods in it’s order except that it has a hole in the middle of it. The hole is created as the shell grows and splits into lobes that then eventually meet back together and enclose a hollow area. This is odd behavior for a brachiopodand I’ve only seen a handful of genera that have even exaggerated lobes, such as Dicoelosia from the Haragan formation, let alone those that surround a hole. Below are three specimens from the Cretaceous (Hauterivian stage) of Spain that show you the variation in the genera.”

The fact that the fern prothallium resembles a heart has not gone unnoticed:
“Nineteen Species of Fern Named for Lady Gaga”
“At one stage of its life, the new genus Gaga has somewhat fluid definitions of gender and bears a striking resemblance to one of Gaga’s famous costumes. Members of the new genus also bear a distinct DNA sequence spelling GAGA.”
