they were discovered 17 days after the planet itself was discovered.
they discovered pencilene
I`m not sure how it was discovered, but it was discovered by Daniel Rutherford in 1772. I`ll get back to you on how it was discovered... :P
Tough One. I Would Chose Either But I Would Have To Go With Megalodon Because It Is Much Larger Than The Dunkleosteus. Despite The Dunkleosteus Having Tough Armor, Megalodon Could Have Bitten Through Dunkleosteus Easily. And Megalodon Also Had Much More Bigger Speed So It Could Catch Up With The Dunkleosteus Easily. NOTE: THEY DID NOT MEET! Megalodon First Appeared Around In The Miocene Era But Dunkleosteus First Appeared Around At The Devion Era.
The dunkleosteus lives in the warmer climates and was Thoth to swim in the shallow
no, it lived long ago
Dunkleosteus
probably whale would win
The largest placoderm,or armored fish, is Dunkleosteus terelli
lack of food and too much shallow water
Megalodon, they were larger,heavier, and stronger bite force.
Pander's Fish (Panderichthys) EusthenopteronObruchevichthys Elpistostege Ceratodus Dunkleosteus
it lived in salt because it ate sharks and other fish
Being in the vicinity of a Dunkleosteus, a large armored fish that liked to eat.
A dunkleosteous is a fish that lived in the water. during the devonian period They could be atleast 50 ft. long and could open their mouths 50 times in one second.
