  Haikouella - Wikipedia, the free encyclopedia
Haikouella does not have bones or a movable jaw, but it otherwise resembles vertebrates.
Almost certain fish Haikouichthys and Myllokunmingia have been found in the same beds.
Suspected hemichordates (more primitive chordates) are also known from these deposits as well as from the Middle Cambrian Burgess Shale of British Columbia.

 Report of GeoScience Research Center: Vol.1
This is a primitive fish that has many similarities to the living hagfish.
Along with Haikouichthys, Myllokunmingia is among the oldest vertebrate animal ever found.
The publication of this discovery in the international scientific journal Nature (4th Nov. 1999) has aroused great interest in the palaeontological community, as these fossils extend the known time-span of the vertebrates back another 50 million years.

 Fauna and Flora
Myllokunmingia was about 3 cm in length and showed a head, gills, dorsal fin and tail.
Most recently, the discovery of a new specimen indicates that Myllokunmingia and Haikouichthys are in fact the same species.
They are subsequently amalgamated under the first name (Myllokunmingia) and may be considered a primitive ancestor of the vertebrates.

 Palaeos Vertebrates 020.000  Craniata Overview
A very early craniate, Myllokunmingia from the Cambrian of China, is badly illustrated in the figure at right.
Since there is no really good reason to suppose that Haikouella belonged to this clade, we treat as a sort of "craniatomorph," but not a craniate.
Myllokunmingia, from about the same time and location, probably is a crown group craniate.

Characters: Neural crest cells, somites, gills with cartilagenous or bone supports (absent in Myllokunmingia?), tripartite brain and paired cranial sense organs, cranium with anterior notochord, semi-circular canal(s), 1 heart, kidneys.
(1999) of Myllokunmingia from the Lower Cambrian of South China is generally what one might have expected of a very primitive craniate.
The state of preservation is also insufficient to state whether Myllokunmingia had eyes, a single heart, an anterior notochord, or even a brain, so that the exact position of this fossil is uncertain.

They are identifiable, say the scientists, because of their gills and a zigzag arrangement of muscles called myotomes, which are only found in fish.
One of the creatures, Haikouichthys ercaicunensis, has gills which are supported by gill bars and the second, Myllokunmingia fengjiaoa, has a more primitive arrangement of gills, but with a series of identifiable pouch-like structures.
Professor Simon Conway Morris, of the Department of Earth Sciences, University of Cambridge, and Professor Degan Shu, of Northwest University, in Xi'an, China, have been analysing the fossils, along with eight other scientists from China.

 Waking Up to the Dawn of Vertebrates, Science News Online (11/6/99)
Both the Chinese specimens have a zigzag arrangement of segmented muscles—the same type of pattern seen in fish today, reports Degan Shu of Northwest University in Xi'an, China, and his colleagues.
The fossils, named Myllokunmingia and Haikouichthys, also have a more complex arrangement of gills than the simple slits used by amphioxus, according to the team's report in the Nov. 4 Nature.
Although the ancient Chinese animals qualify as vertebrates, they lack the bony skeleton and teeth seen in most, but not all, members of this subphylum today.

 DARWINISM-WATCH.com - Responding Evolutionist Propaganda in the Media
This reveals that evolutionists, who in any case support a totally indefensible scenario (in other words the illogical claim that a complex design such as that in teeth could be the work of chance mutations), are now obliged to propose that this scenario actually took place many times.
Let us also recall here that evolutionists already face an insuperable dilemma when it comes to the origin of fish: it has been calculated that the fossil fish Haikouichthys ercaicunensis and Myllokunmingia fengjiaoa found in China in 1999 are some 530 million years old.
That figure takes us back to the exact middle of the Cambrian Period, when just about all the known animal phyla emerged.

 News & Notes - Does God Exist? - JanFeb00
We have also pointed out that there are a number of backboned animals that appear very early in the fossil record.
In Science News (November 6,1999, page 292) is an article about a fossil called Myllokunmingia and another called Haikouichthys which have all the properties of chordates but are in rocks that are 530 million years old.
This article agrees with the point that we have made in the past that all life groups appear at the same time in the fossil record--a point also made in the biblical record.

 Chapter 7 The Early Vertebrates   (Site not responding. Last check: 2007-09-19)
There are two different genera: Haikouichthys, which looks like a lamprey, and Myllokunmingia, which looks like a hagfish.
Chordates were already known from the Chengjiang fauna, specifically in the form of Yunnanozoon, which is very much like Pikaia from the Middle Cambrian Burgess Shale and the living amphioxus, Branchiostoma, with recognizable gills and the characteristic zig-zag pattern of muscle bands that makes these animals chordates.
And Myllokunmingia has pouch-like structures associated with its gills, which also makes it a jawless fish rather than a chordate.

It has only been recorded from the Chengjiang biota.
Myllokunmingia is one of the most celebrated fossils from the Chengjiang biota, as it is the earliest known vertebrate.
It could certainly swim, though its mode of feeding is as yet unknown.

Myllokunmingia and Haikouichthys, two early vertebrates that still lack a clear head and bony skeletons and teeth.
They differ from earlier invertebrate chordates in having a zigzag arrangement of segmented muscles, and their gill arrangement is more complex than a simple slit (Monastersky 1999).
