| When did the pike and muskie both appear in the fossil record. At one time they would have been one
species? When did they population seperate and adapt to new type environments / spawning locations? |

| Hey, when I'm landing a nice fish this weekend I'll think of you in traffic by the cities.
Next time on the shield I'll have a full report for you on esox evolution. That'll make you and dynamite Dave happy! |

Location: Mauston, Wisconsin | Question #1- There seems to be some debate ~ The Late Cretaceous Period of the Mesozoic Era: 65.5 to 98.9 million years ago. Oldest fossil record of present day ESOX Masquinongy's ancestor -"ESOX tiemani"- found in Canada and dated @ ~62 million years.
Question #2. It seems muskies (ESOX Masquinongy) @ ~ 25 million yers ago may have been first then pike (ESOX Lucius) developed later.
A very interesting article/paper->

I have been wondering why the Musky seems to be less prudent than the Pike, like when approaching a boat, and probably also less adoptable. Could this have something to do with a more primitive evolutionary stage, if appearing earlier than Esox Lucius?

Works for me.
Recently, it was the ice age glaciers that dug the holes and very long trenches for 'em to live. How they got in there, is quite another story. |
