Buckland did describe the jaw of a small primitive mammal, Phascolotherium, that was found in the same strata as Megalosaurus.
Data on helmet use in all jurisdictions were available from the 2009/2010 CCHS via the following questions: "In the past 12 months, have you done any bicycling?" and if yes, "When riding a bicycle, how often do you wear a helmet?" The proportions who reported wearing a helmet always or most of the time were calculated for the same strata as hospitalisation rates.
After five years in which Minaya's Mets seemed to travel in the same stratum as the Yankees, if not occasionally on a higher plane, the old order has been re-established.
These are saved for the end of the book, when we learn that Gatsby, originating from a penniless Midwestern family, had courted Daisy in the hopes of marrying her, letting her "believe that he was a person from the same stratum as herself".
As further evidence for a one-time mass extinction, Erwin's group found volcanic dust in the same stratum as the extinct species, as well as a change in the carbon isotope profile, an indication that fewer plants were alive and photosynthesizing.
The largest eosimiid, Bahinia, is from the Pondaung Formation, the same stratum as Afrasia, and the morphology of its molars bridges the gap between the more primitive molars of Eosimias and the more derived molars of the later Eocene African simians.
Control days were defined as the same day of the same stratum as the case day.
The one hospital that declined to participate was replaced by an alternative randomly selected hospital from within the same stratum, as identified in the earlier study.
First, the time-stratified approach was applied by dividing the study period into 2-month strata using a referent selection matched on the same day of the week with 14-day intervals within the same stratum as the case day.
The pseudo-partial likelihood in (4) is modified by replacing R j by R sj, the set of individuals in the subcohort who are at risk at t j and in the same stratum as the case which occurred at time t j, plus the case itself at t j (if the case is not in the subcohort).
The control sample was obtained by selecting a random patient to match each patient in the suicide death sample on age (+/- 5 years) from those in the same stratum as the case patient and alive on the date of suicide (i.e., index date).
