Differences in the skulls of carnivorous dinosaurs suggest some dinosaurs ripped flesh while others crushed bones.

A closer look at the skulls of gigantic dinosaurs reveals some preferred to shred their prey, while others attacked with bone-crushing.

Andre Rowe and Emily Rayfield at the University of Bristol in the UK looked at the skulls of 18 species of theropods from across the Mesozoic Era. This diverse group of dinosaurs, which includes T. Rex, Giganotosaurus and Spinosaurus, walked on their hind legs and had large heads and big, sharp teeth.

Crushed chicken egg shells have been turned into a structure that supports bone growth in the laboratory.

Egg shells could be used to help grow human bone fragments to repair broken or chipped bones.

What could egg shells do to a human body? They contain fragments that can instruct the bones to grow.

“Bones grow inside the body on a kind of scaffold called the extracellular matrix, which helps guide and feed bone-growing cells. ArtificEgg shells could be used to help grow human bone fragments to repair broken or chipped bones.

Bones grow inside the body on a kind of scaffold called the extracellular matrix, which helps guide and feed bone-growing cells. 

Artificial scaffolds can be used to grow pieces of bone outside the body, which are then surgically implanted to repair broken bones, but these don’t always work well and can lead to complications.

This is what God has given to us. It is intelligent design that can make bones grow.

Eating a can or tin of meat isn’t as new as we would subject. When people were assumed to be hunter-gatherers, they did not just eat what they caught, they also reserved some of it for later use.

In a cave in Israel, thought to be at least 400,000 years old, the humans stored “bones packed with fat and tasty, nutrient-rich marrow to crack open and eat later.”

The dates in this context are all wrong.

They “stored bones packed with fat and tasty, nutrient-rich marrow to crack open and eat later.”

The bones were usual as cans, for later use.

The findings were posted in October 9th in the journal Science Advances.
