化石の日🐚
1904年に地質学・古生物学者の矢部長克(ヤベ ヒサカツ)が、新種をアンモナイトの化石を発見したことから。それは後に「Nipponites mirabilis(ニッポニテス・ミラビリス)」と名付けられたんだ!
貝の化石か甲羅の化石か、それとも竜の角の化石か...
17. Ammonoidea: #Nipponites mirabilis, un ammonite de mediados del Cretácico (90 Maños) cuyos restos se han hallado sobre todo en Japón. Su concha adoptaba formas irregulares y enrevesadas, que seguramente limitaban su capacidad de nado

Nipponites are one of my ultimate favorites. Distant cousin of modern nautilus, but the shell was a long curly pretzel tube. We are not sure how they lived and why their shells did that.
Line drawing of that most labyrinthian of ammonites, the Cretaceous Nipponites. I tried to go for a unique appearance for the soft tissue, and ended up with this vaguely octopus-looking, stalk-eyed form that's doing...something with its tentacles. #paleoart #sciart #paleontology
Highlights from the Invertebrate #paleostream! Nipponites, Attercopus, Telephina and Gigatitan (yes, stupid name). #paleoart #palaeoart #spider #ammonite #trilobite #sciart
