Trees sway in the breeze,

as it whispers dark secrets

of lands from afar.

My Cairn

My Cairn

Cairns are piles of stones used by many different cultures for various purposes. 

They are generally found in wilderness areas such as mountains and deserts to help guide travelers.  or mountainous regions, and also in barren desert and tundra areas as well as on coasts.  Tibetans also use cairns known as ovoos for Buddhist ceremonies. 

So make a cairn.  Help out a fellow hiker and practice the patience-testing art of cairn making.

Radar Storm Front

Radar Storm Front

Yesterday, a big storm front came through New York and hit us pretty hard.   I captured this RADAR image off of Accuweather.  We use this fascinating technology just about every day, but few know what it is or how it works. 

Radar is an acronym that stands for RAdio Detection And Ranging.  The actual machine is a parabolic dish.  The radar itself does not delineate between rain and snow but AccuWeather’s proprietary algorithms do, based on atmospheric conditions.

RADAR uses electromagnetic waves to identify the range, altitude, direction, and speed of objects, including weather fronts.  When they come into contact with an object are scattered in all directions.  When it returns to the RADAR disc, the wavelength (which also changed) is amplified and measured to determine the above characteristics of the object.

A Pangolin  is a mammal related to anteaters. Pangolins have large keratin scales covering their skin, making them very unique.  When threatened, these creatures roll up in a defensive ball.  They are found in tropical regions of Africa and Asia.  They are primarily nocturnal animals which hunt at night. 

Their numbers, although relatively strong, is rapidly decreasing due to bushmeat hunting and traditional medicine.

What killed the dinosaurs?

It is believed that dinosaur extinction was part of a mass extinction brought about by two massive destructive events. The first of these was the collision with the Earth of a meteorite landing in what is now the Yucatan Peninsula, of Mexico. This was followed by an enormous volcanic eruption which split what is now India in half.

How many types of dinosaur were there?

At present over 700 different species of dinosaurs have been identified and named. However palaeontologists believe that there are many more new and different dinosaur species still to be discovered.

The Tallest Dinosaur

The tallest dinosaurs were the Brachiosaurid group of sauropods. Their front legs were longer than the rear legs giving them a giraffe-like stance. This combined with their extremely long necks, which were held vertically, meant they could browse off the tallest trees. Brachiosaurus – the most well known of the group – was 13 metres tall. Sauroposeidon was massive and probably grew to 18.5 metres tall making it the tallest dinosaur.

The Fastest Running Dinosaur

The speediest dinosaurs were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.

The Oldest Dinosaur

The oldest dinosaurs known are 230 million years old, and have been found in Madagasgar. As yet they have not been formally named. Before this Eoraptor, meaning “dawn thief” had held the title at 228 million years.

The Longest Dinosaur Name

The dinosaur with the longest name was Micropachycephalosaurus meaning “tiny thick-headed lizard”. Its fossils have been found in China, and it was named in 1978 by the Chinese palaeontologist Dong.

The Fiercest Dinosaur

Tyrannosaurus rex looked the most ferocious of all the dinosaurs, but in terms of overall cunning, determination and its array of vicious weapons it was Utahraptor that was probably the fiercest of all. Utahraptor measured about 7 metres, and was a very powerful, agile and intelligent predator.

The Heaviest Dinosaur

The heaviest dinosaur was Brachiosaurus at 80 tonnes. It was the equivalent to 17 African Elephants. Brachiosaurus was 16m tall and 26m long and is the largest dinosaur skeleton to be mounted in a museum.

Smallest Dinosaur Egg

Dinosaur eggs come in all shapes and sizes. They tend to be ovoid or spherical in shape and up to 30cm in length – about the size of a rugby ball. The smallest dinosaur egg so far found is only 3cm long. Once the egg has been fossilised it will become hard like rock, but it will retain a structure of its own.

The Smallest Dinosaur

The smallest fully-grown fossil dinosaur is the little bird-hipped plant-eater like lesothosaurus, which was only the size of a chicken. Smaller fossilised examples have been found, but these are of baby dinosaurs.

The Most Smartest Dinosaur

One of the most intelligent dinosaurs was Troodon. It was a hunting dinosaur, about 2 metres long, and had a brain size similar to that of a mammal or bird of today, stereoscopic vision, and grasping hands

The Dumbest Dinosaur

Stegosaurus had a brain the size of a walnut – only 3 centimetres long and weighing 75 grams. However, comparing brain size to body size sauropodomorphs, like Plateosaurus, were probably one of the dumbest dinosaurs.
