Dinosaur Soft Tissue Preservation Explained By Iron In Hemoglobin

There seems to be a lot of confusion among creationists about "Soft Tissue" found inside dinosaur fossils and what it means. Part of this confusion is caused by creationist publications that misrepresent the data and leave out important information, as well as the fact the preservation has been explained. Many do not even understand that "soft tissue" is a type of tissue and not the state it was found in. In every case discovered so far, iron from hemoglobin has been present and it has been determined to be the preserving agent.

This is from a 2013 article on the topic:
 
"Iron is an element present in abundance in the body, particularly in the blood, where it is part of the protein that carries oxygen from the lungs to the tissues. Iron is also highly reactive with other molecules, so the body keeps it locked up tight, bound to molecules that prevent it from wreaking havoc on the tissues.
 
After death, though, iron is let free from its cage. It forms minuscule iron nanoparticles and also generates free radicals, which are highly reactive molecules thought to be involved in aging.
 
"The free radicals cause proteins and cell membranes to tie in knots," Schweitzer said. "They basically act like formaldehyde."

Dr. Mary Schweitzer was able to recreate the process in the lab and she demonstrated it only took a matter of weeks to reach a state of preservation. Once preserved with iron and encased in permineralized bone, the preserved soft tissue could last indefinitely depending on environmental conditions.
 
Several independent studies support Schweitzer's hypothesis about the role iron from hemoglobin plays in preserving soft tissue:
 
1) 247 Million Year Old Reptile Tissue Preserved By Iron In Hemoglobin.
 
Spectroscopic Studies on Organic Matter from Triassic Reptile Bones, Upper Silesia, Poland Published: March 15, 2016
 
"The preservation of molecular signals of proteins within the "blood vessels" was most likely made possible through the process of early diagenetic iron oxide mineralization."

2) 46 Million Year Old Mosquito Preserved By Iron In Hemoglobin
 
"Heme, the oxygen-carrying group of hemoglobin in the host’s blood, was identified in the abdomen of the fossil mosquito by nondestructive mass-spectrometry analysis. Although large and fragile molecules such as DNA cannot survive fossilization, other complex organic molecules, in this case iron-stabilized heme, can survive intact and provide information relative to the mechanisms of the fossilization process.

3) 195 Million Year Old Dinosaur Collagen And Protein Preserved By Iron In Hemoglobin.
 
"The in situ synchrotron radiation-based Fourier transform infrared (SR-FTIR) spectra exhibit the characteristic infrared absorption bands for amide A and B, amide I, II and III of collagen. Aggregated haematite particles (α-Fe2O3) about 6∼8 μm in diameter are also identified inside the vascular canals using confocal Raman microscopy, where the organic remains were preserved. We propose that these particles likely had a crucial role in the preservation of the proteins, and may be remnants partially contributed from haemoglobin and other iron-rich proteins from the original blood."

There are several more examples. Preserved soft tissue inside dinosaur bones is a non-issue for evolution and is not evidence the Earth is young.
