Were Dinosaurs Warm Blooded?
Psalm 147:2-3
"The LORD builds up Jerusalem; He gathers together the outcasts of Israel. He heals the broken hearted and binds up their wounds."
Dinosaur fossil hunters and paleontologists have long debated whether dinosaurs were warm- blooded or cold-blooded. With reptile characteristics, it was expected that dinosaurs would be cold-blooded. Yet, some evidence indicated that they must have been warm-blooded. The problem is that their soft organs are almost never fossilized.
The words "almost never" are important. A dinosaur liver and diaphragm – the soft parts – were recently found fossilized. Fossilization of soft organs is a testimony to the rapidity with which the dinosaurs were encased in the mud that later hardened to rock. Now a fossilized dinosaur heart has been discovered in South Dakota within the chest cavity of a fossilized Thescelosaurus. Once researchers recognized that the stone within the chest cavity might be a heart, they x-rayed it. X-rays revealed a four-chambered heart with one aorta. Reptiles have two aortas. In other words, Thescelosaurus had a heart constructed like the hearts of warm-blooded animals. This kind of heart is more efficient in delivering oxygen to the body. This in turn supports a more active lifestyle and higher metabolic rates. Based on the structure of Thescelosaurus's heart, many scientists have concluded that it was indeed warm-blooded.
The same Creator who made the dinosaur's heart is able to heal our hearts when they are broken by sorrow. It is He Who heals our broken hearts through the forgiveness of sins that is found in Jesus Christ.
Prayer: Thank You, Father, for bringing Your power into my life. Amen.
