NH Notes: Gall Mites in Amber Similar but Not the Same As Today

Preserved gall mites in amber found encased in rocks at the base of mountains in Italy.

Today Creation.com (Creation Ministries International) published a story about the amazing preservation of clearly identifiable gall mites.   My Facebook feed proclaimed the following:    ”Gall mites magnificently preserved in amber ostensibly 230 million years old are just the same as mites found alive today” with a link to the story HERE.   The gist of the article […]

NH Notes: Answers in Genesis and a Mountain of Extraterrestrial Dust

mars-whole-planet

How long would it take for falling dust to accumulate into a mound 2 1/2 miles tall?  Answers in Genesis has commented (Wind, not water, may have built the Martian Mount Sharp) over the weekend on the same research article that I referenced in my post last week (NH Notes: Did Wind and Dust Create a […]

NH Notes: Did Wind and Dust Create a 15,000 Foot Mountain in Gale Crater?

mars-rover-landing-sequence

Large depressions, layers of rocks, precipitated minerals in rock cracks, erratic rocks strewn about, mountains inside of craters: these are just a few examples of the diversity of landscapes on Mars that the Curiosity rover has discovered and been investigating the past six months.   The mountain at the center of the crater that Curiosity […]

NH Notes: Mysterious Noises in My Attic Finally Explained

NORTHERN-FLYING-SQUIRREL-3

A few nights ago I finally decided it was time to find out what had been making periodic strange noises in my attic at night for the last couple of months.  I had looked up there once before and couldn’t find any signs of anything unusual so I thought it was just in the gutters […]

NH Notes: Context is Key For Interpreting Large Fossil Find in Spain

Killer-cave-may-have-enticed-then-trapped-ancient-carnivores

One small site in Spain has yielded 1800 fossil bones from at least 18 species of extinct large animals. That is the update today about a fossil site that has been under investigation for 10 years.  The site represents one of the best sites for fossil carnivores because of the unique circumstances under which it […]

NH Notes: A Trunk and Tusk-Challenged Fossil Elephant

The extinct elephant Deinotherum was quite a bit larger than even the largest elephant today. It's bones have been found from Asia to Europe and through the upper half of Africa.  This report from Kenya is the first time I've seen their bones associated with evidence of human occupation.

I have been thinking about Elephants the last couple of days and may write more about elephant following in the vein of my recent posts on horses.  For now I just want to introduce you to one really weird extinct elephant.  I call it an elephant because of its obvious similarities but just like with […]

NH Notes: Fossil Wasp Cocoons in Dinosaur Eggs – Evidence of a Complex Ecology

What happened to huge dinosaur eggs that were either abandoned or broke prematurely?  You might think that this is a question that is impossible to answer, but there have been dinosaur eggs that have been discovered with intriguing evidence of scavenging of various forms.   I recently came across a report from 2011 that I […]

NH Notes: Identifying Pseudoscience – Velikovsky and Catastrophism

The Pseudoscience Wars by Michael Gordin

What is pseudoscience and how does one recognize it?  Scientists and philosophers have long struggled to answer this difficult question.  A book published last year,  The Pseudoscience Wars: Immanuel Velikovsky and the Birth of the Modern Fringe by Michael Gordin,  helps to further refine our understanding of what pseudoscience is by examining the rise and fall of […]

NH Notes: Fossilized Animal Borrows in Argentina

This is a photograph of a typical borrow complex found in Triassic formations in Argentinia.  The scale bar in the pictures is 10 centimeters.  Horizontal shafts are labeled "A" and vertical shafts that continued doen into rock below or would have gone up to the surface are labeled "B". This is Fig 3 from: Colombi CE, Fernández E, Currie BS, Alcober OA, et al. (2012) Large-Diameter Burrows of the Triassic Ischigualasto Basin, NW Argentina: Paleoecological and Paleoenvironmental Implications. PLoS ONE 7(12): e50662. doi:10.1371/journal.pone.0050662
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0050662.

A quick natural history note this morning.  I was looking for some information for my class and ran across this image which was just too cool not to share.  It shows a form of trace fossil. Trace fossils are not fossilized remains of actual organisms but instead are evidence of the past presence of organisms. […]

NH Notes: A Follow-up About Heat Sharing Huddling Penguins

I’m posting a short follow-up to a story about huddling penguins that I wrote about a few weeks ago (Heat-sharing Huddling Penguins – A Benefit to Selfish Behavior?).  I was pointed to a really fascinating set of videos that show emperor penguins in the process of forming huddles.  You can see these videos embedded in […]
