Druhohory jsou drsná krajina plná predátorů. Kdo však pozná tuto krajinu, objeví její skrytou krásu.

Megarachne

5. února 2013 v 14:37 | Dinosaur12 |  Jiná prehistorická zvířata
MEGARACHNE
(obří pavouk)

délka: 45cm
období: Svrchní karbon (315 ma)
naleziště: Brazílie
řád: Eurypterida (kyjonožci)
čeleď: Mycteroptidae

Megarachne servinei byl původně popsán jako velký druh pavouka. Při pozdějších výzkumech se však
ukázalo, že jde o blízkého příbuzného velkých mořských štírů, žijícího nejspíš ve sladké vodě,
živícího se prohrabáváním dna. Pravděpodobně se stával obohacením jídelníčku tehdejších jezerních
a říčních predátorů, jako byl např. crassigyrinus, nebo proterogyrinus. Na rozdíl od svých velkých
mořských příbuzných, nedisponuje megarachne veslovitými končetinami, což naznačuje, že mohl aktivně
žít i na souši. To je ale čistě moje hypotéza a nerad bych jí jako laik někomu vnucoval.
