Jaekelopterus rhenaniae catching a Ventastega curonica
and Chasmataspis laurencii
by Guillermo Navalón Ferná.
1- “A dramatic scene in the Middle Devonian where you can see the huge pterygoid eurypterid Jaekelopterus rhenaniia (2,5- 3 m) hunting the tetrapodomorph fish Ventastega curonica. This reconstruction is highly hypothetical and is mostly based on its relative Pterygotus, much better known. In contrast to another eurypterids, Jaekelopterus lived in fresh water and some scientists think that it was able to walk on land. Done for an university investigation about arthropod evolution.”
2- “Chasmataspis laurencii from the Ordovician in Unites States. Thought to be in its discovery a young specimen of a eurypterid, now we know that it is a representative species of a “sister” order of eurypterid and xiphosurans, much more related with eurypterids than xiphosurans.
The long metasome is thought to be used as a stabilizer in its brief incursions to the surface.
Done for an university arthropod-evolution investigation in about two hours of hard work.”
