The Tertiary is a an out-of-date term for a geologic period 65 million to 1.8 million years ago. The Tertiary covered the time span between the superseded Secondary period and an out-of-date definition of the Quaternary period. The period began with the demise of the non- avian dinosaurs in the Cretaceous–Tertiary extinction event, at start of the Cenozoic era, spanning to beginning of the most recent Ice Age, at the end of the Pliocene epoch. The term Tertiary was first used by Giovanni Arduino in 1759. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in northern Italy.[4] Later a fourth period, the Quaternary, was applied. In 1828, Charles Lyell incorporated a Tertiary period into his own, far more detailed system of classification. He subdivided the Tertiary period into four epochs according to the percentage of fossil mollusks resembling modern species found in those strata. He used Greek names Eocene, Miocene, Older Pliocene and Newer Pliocene. Although these divisions seemed adequate for the region to which the designations were originally applied (parts of the Alps and plains of Italy), when the same system was later extended to other parts of Europe and to America, it proved to be inapplicable. Therefore, later the use of mollusks was abandoned from the definition and the epochs were renamed and redefined. See Zachos 2001 At the beginning of the period, mammals replaced reptiles as the dominant vertebrates. Each epoch of the Tertiary was marked by striking developments in mammalian life. The earliest recognizable hominoid relatives of humans, Proconsul and Australopithecus, also. Modern types of birds, reptiles, amphibians, fish, and invertebrates were either already numerous at the beginning of the period or appeared early in its history. Modern families of flowering plants evolved. Marine invertebrates and non-mammal marine vertebrates experienced only modest evolution.

1. Do your qualifications disqualify you from potential jobs?
October 10, 2008
For many generations the mere fact that someone had a university degree – any degree- was enough to guarantee them a well-paying job. A degree was not only proof of knowledge gained, but also of discipline and stamina. Now, things are somewhat different. University degrees are still prized and in some fields (medicine and law) absolutely necessary, but for many companies, practical skills are starting to overshadow theoretical knowledge.

2. Antique Clocks - Will Prices Continue To Rise? Only Time Will Tell
September 16, 2008
The same antique clocks may be called various names by different experts depending on what region of the world they live in, which can get really confusing. For example, what the British call a "bracket clock" is actually identical to what American dealers call "shelf clocks" or "mantle clocks."
The primary categories of antique clocks can be further divided into secondary and tertiary subcategories. For example, within the wide classification of beehive clocks, one will also find classifications like ripple beehive and gothic beehive. As another example, the wide classification of drop tru...

8. Anesthesia and analgesia wonder still
September 08, 2007
Are stronger medication seeping into dentistry? The useage of compounds like Versed, demerol and fentanyl were not so common five years ago in dentistry. Why the change? Bupivacaine 0.5%, a tertiary amide compound commonly used to induce nerve block anesthesia in dental procedures, continues to mystify pharmacologist with its dual properties of producing analgesia after soft tissue anesthesia has worn off. Although structurally it resembles other amides such as lidocaine; however, in the hydrophilic section, it contains four extra carbons. We suspect this is responsible for its unique mod...

9. Thyroid disease secondary, to other health problems
April 14, 2007
We know that thyroid disease is a problem that can arise in special situations or can be a problem secondary to other diseases.
Secondary or tertiary types of hypo or hyperthyroidism are treated as same as primary cases of hypo or hyperthyroidism. During thyroid replacement TSH cannot be relied upon. In these cases free T4 is used. For these situations the replacement of deficient hormones might always mean a solution.
Central hyperthyroidism is the consequence of a TSH secreting pituitary tumor or a TSH resistance. These cases are pretty rare. In the first one of the cases mention... (read more)

Research reports in primary sources are written by investigators, are subject to peer review, provide details about methodology and findings, and are often rife with jargon.
