Pygope (original) (raw)
Pygope is an extinct genus of brachiopods belonging to the family Pygopidae. These brachiopods lived in open sea from the Jurassic Period, Kimmeridgian age (152.1–157.3 mya) up to Cretaceous Period, Barremian age (125.0–~129.4 mya). Some of the species are characterised by a smaller or larger perforation through the entire shell in older specimens, while others just have a depression somewhere on the midline. Younger specimens of the perforated species develop a heart-shape and subsequently both extensions merge, thus encircling a central passage which is in fact entirely outside the shell.

| dbo:abstract | Pygope is an extinct genus of brachiopods belonging to the family Pygopidae. These brachiopods lived in open sea from the Jurassic Period, Kimmeridgian age (152.1–157.3 mya) up to Cretaceous Period, Barremian age (125.0–~129.4 mya). Some of the species are characterised by a smaller or larger perforation through the entire shell in older specimens, while others just have a depression somewhere on the midline. Younger specimens of the perforated species develop a heart-shape and subsequently both extensions merge, thus encircling a central passage which is in fact entirely outside the shell. (en) Pygope Link, 1830 è un genere di Brachiopoda estinti appartenenti alla famiglia . Si rinvengono nei depositi marini del Giurassico superiore e Cretaceo inferiore (in un periodo compreso tra i 163 e i 97 milioni di anni fa). La conchiglia è molto caratteristica e la sua forma ne facilita il riconoscimento. Il sottile guscio bivalve è biconvesso a contorno trigonale e arrotondato, con espansioni alari laterali che, durante la crescita, si saldano anteriormente lungo una linea mediana formando una depressione ellittica o, talora, una perforazione centrale. La valva peduncolare (ventrale) presenta un piccolo umbone piuttosto sporgente e recante un foramen circolare, da cui fuoriusciva il peduncolo. L'aspetto esterno delle valve è liscio e privo di ornamentazione mentre, all'interno, sono spesso ben visibili le impronte dei canali del mantello con numerose biforcazioni. Questi organismi colonizzavano fondali marini a profondità variabili (fino alla zona di transizione tra piattaforma continentale e bacino), in ambienti ad abbondante sedimentazione calcarea. (it) |
