Large Ancient Platypus With Teeth
We see the platypus as a quiet curious animal always on the go, but millions of years ago it was twice as big and had vicious teeth. It hunted turtles crayfish and frogs. Paleontologists have called it Platypus Godzilla because it would have been quite vicious.
The modern platypus, Obdurodon tharalkooschild, is only half a meter long. Its quiet, secretive life could indicate that it is heading for extinction. Identifying platypus fossils is easy if teeth are found, because they are so different from other species.
Platypus teeth are blunt. The animals must have "bruised" their prey to death. Fossils of the ancient platypus were not ancestors of modern platypus. They were a side branch "experimenting' with being a larger size.
Just why platypus millions of years old had functioning teeth while modern ones have virtually lost theirs is not known. Despite being good a hunter Godzilla did itself go extinct. Modern tharalkoo live in a narrow niche. If there is drastic change in the environment they will perish.

Fish Fossil Sheds More Light
There are new facts about the evolution of fish. An ancient fish fossil has provided preserved muscle tissue. European and Australian scientists have examined a placoderm fossil 380 million years old. Early fish did not have moving jaws with joints. Their mouths were fixed partially open, though they could still move.
Jaw structure was presumed to be like sharks, because that was taken to be a living example. The fossil has changed this assumption. It shows a pronounced shoulder structure. From this girdle neck muscles attached to a dermal joint. So the head moved relative to the body but the jaw did not. Sharks do not have joints in the neck - their necks are flexible.
Another difference is musculature in the abdomen much like four-limbed vertebrates such as horses. Rather than being a evolutionary step for four-legged animals it was fully developed by placoderms, the first vertebrate with armoured plates and no teeth.

Your Body Runs Without You
The human body runs on its own. Think of the times your mind is working on a problem and during the evaluation process your body is continuing with daily routine tasks. It happens every day. You reach a conscious conclusion on a problem and then wonder have I had a cup of coffee? Oh yes, you have - you can still taste it.
The body can you give you unwanted pain as well. Your body can do things totally out of your control that really "bug" you, like teeth that hurt, hiccups, stitch, pins and needles or cramp.
Some get a headache or painful teeth when they eat or drink something cold. This is due to sensitive nerve endings in teeth. You can use special toothpaste that takes months before it becomes effective. In the mean time stay away from cold things.
Hiccups is caused by eating and drinking too fast, or taking in air. It can also be caused by becoming suddenly nervous. The only real known cure it to take beta blockers. Though you have to wait until the medication takes effect.
A stitch occurs during exercise when your body tries to tell you that is enough. Stopping the strenuous activity will "cure" the malady.
Pins and needles happens when the blood supply to nerve endings in the limbs is constricted. Get up and move around then normal feeling will return to the "dead" limb.
The cause of cramp is unknown. Dehydration and being unfit are not factors - well hydrated supremely fit sports people get afflicted with it. Spasmodic constricting muscles hurt. The only thing you can do is wait for them to settle down - perhaps more beta blockers.
Your body is a complex machine. Look after it. Service it well. The model you have has its own quirks. Just learn to live with them.

Donkey Attack
People have much affection for the humble donkey. It is seen as being quiet and friendlier than the horse. Donkeys do, however, kick and bite when they are made to do something they don't want to do, or are prodded and poked unnecessarily.
A Swedish lady kept a donkey with her horse. She thought it would make the horse happier and quieter. One day she separated the donkey from the horse. It became violent biting the lady's thumb. Furthermore, its teeth latched on firmly. She could not get it free the animal's mouth. Help arrived and a crowbar was used to pry the thumb away from the vicious bite.
The owner was taken to the nearest hospital and they found no breaks in her bones. She was bandaged, given a tetanus injection and taken home. A week late puss was oozing from the wound - she had not been given antibiotics. A sample taken from her hand showed the presence of Staphylococcus hyicus. This is common is the mouths of horses, but was not known to cause infection in humans.
The experience left the woman with a permanently numb area at the tip of her thumb. When you next feel like patting an animal that appears to be mild and friendly, just of think of the pain endured with the damaged thumb.
