- Tree of life (biblical) (Wikipedia)
In Judaism and Christianity, the tree of life (Hebrew: עֵץ הַחַיִּים, romanized: ‘ēṣ haḥayyīm; Latin: Lignum vitae) is first described in chapter 2, verse 9 of the Book of Genesis as being “in the midst of the Garden of Eden” with the tree of the knowledge of good and evil (עֵץ הַדַּעַת טוֹב וָרָע; Lignum scientiae boni et mali). After the fall of man, “lest he put forth his hand, and take also of the tree of life, and eat, and live for ever”, cherubim and a flaming sword are placed at the east end of the Garden to guard the way to the tree of life. The tree of life has become the subject of some debate as to whether or not the tree of the knowledge of good and evil is the same tree.
- Dimetrodon (Wikipedia)
Dimetrodon (/daɪˈmiːtrəˌdɒn/ or /daɪˈmɛtrəˌdɒn/; lit. ’two measures of teeth’) is an extinct genus of non-mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early [Permian](Permian period, around 295–272 million years ago. With most species measuring 1.7–4.6 m (5.6–15.1 ft) long and weighing 28–250 kg (62–551 lb), the most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It was an obligate quadruped (it could only walk on four legs) and had a tall, curved skull with large teeth of different sizes set along the jaws.
