Lobopods resemble something like a velvet worm which means these worms have legs. A pretty remarkable discovery, the Lobopod fossil was found in the midwest, namely in Illinois. Previously these animals were discovered in places like the Burgess Shale in Canada and also in Sweden.
There has been some confusion about the worms in terms of where they fit in the evolutionary tree (taxonomy). Evolutionists have narrowed it down to ancestors of arthropods or related to modern water bears. The discovery was a surprise to Paleontologists who thought these animals had died out in the middle Cambrian, but recently, an exquisitely-preserved fossil has been discovered in Carboniferous rock in Illinois!
In Current Biology…
“Lobopodians, a nonmonophyletic assemblage of worm-shaped soft-bodied animals most closely related to arthropods, show two major morphotypes: long-legged and short-legged forms.”
“The morphotype with stubby, conical legs has a long evolutionary history, from the early Cambrian through the Carboniferous, including the living onychophorans and tardigrades. Species with tubular lobopods exceeding the body diameter have been reported exclusively from the Cambrian; the three-dimensionally preserved Orstenotubulus evamuellerae from the uppermost middle Cambrian “Orsten” (Sweden) is the youngest long-legged lobopodian reported thus far.”
“Here we describe a new long-legged lobopodian, Carbotubulus waloszeki gen. et sp. nov., from Mazon Creek, Illinois, USA (∼296 million years ago). This first post-Cambrian long-legged lobopodian extends the range of this morphotype by about 200 million years. The three-dimensionally preserved specimen differs significantly from the associated short-legged form Ilyodes inopinata, of which we also present new head details.”
“The discovery of a Carboniferous long-legged lobopodian provides a more striking example of the long-term survival of Cambrian morphotypes than, for example, the occurrence of a Burgess Shale-type biota in the Ordovician of Morocco and dampens the effect of any major extinction of taxa at the end of the middle Cambrian.”
No doubt, this remarkable find has increased the complexity (caused a problem) within the framework of evolution. For instance, with the stories of mass extinctions of other animals, this one did fine for supposedly 200 million years without changing.
Of course, the exquisite preservation found with the fossilized details of soft tissues challenges beliefs (in evolution) that these animals lasted nearly 300 million years with all the geologic and climatic changes that supposedly went on during all those years! However, the exquisite preservation of soft tissues does in fact confirm the creationist time frame of a young earth!
And finally, another remarkable thing about this fossil discovery is that the fact that the animal was found in the midwest, which were known to be in Sweden and Canada, shows its wide “range extension” of these tiny creatures!
So these multicellular animals with coordinated legs, bilateral symmetry, a gut, and behavior suited for their life were unchanged, no evolution! And their delicate, little soft-bodied animals that did just wonderful for 200 million years in evolutionary time while other animals were having mass exits from the world along with geological and climate changes in the story of evolution.
Increased complexity in a theory is not confirmation, this discovery of a fossil demonstrates in part, that the story of evolution is not true!
