Question

estimates of tyrannosaurid bite force
which choice best describes data from the table that support barrett and rayfield’s
suggestion?
a the study by meers used body mass scaling and produced the lowest
estimated maximum bite force, while the study by cost et al. used
muscular and skeletal modeling and produced the highest estimated
maximum.
b in their study, gignac and erickson used tooth force interaction analysis to
produce an estimated bite force range with a minimum of 8,000 newtons
and a maximum of 34,000 newtons.
c the bite force estimates produced by bates and falkingham and by cost et
al. were similar to each other, while the estimates produced by meers and
by gignac and erickson each differed substantially from any other
estimate.
d the estimated maximum bite force produced by cost et al. exceeded the
estimated maximum produced by bates and falkingham, even though
both groups of researchers used the same method to generate their
estimates.
the largest tyrannosaurids—the family of carnivorous dinosaurs that includes
tyrannosaurus, albertosaurus, and most famously tyrannosaurus rex—are thought to have
had the strongest bites of any land animals in earth’s history. determining the bite force of
extinct animals can be difficult, however, and paleontologists paul barrett and emily
rayfield have suggested that an estimate of dinosaur bite force may be significantly
influenced by the methodology used in generating that estimate.

Explanation:

To solve this, we analyze each option against the table data:

• Option A: Meers' method (body mass scaling) gave 181,000–233,000 newtons, while Cost et al. (muscular and skeletal modeling) gave 15,000–63,000. So Meers' estimate is higher, but the option says Cost et al. had the highest, which is wrong.
• Option B: Gignac and Erickson's study (tooth - bone interaction analysis) had a range of 8,000–34,000 newtons. This matches the data in the table for their study.
• Option C: Bates and Falkingham's estimate (35,000–57,000) and Meers' estimate (181,000–233,000) are not similar. So this option is wrong.
• Option D: Cost et al. (15,000–63,000) and Bates and Falkingham (35,000–57,000) used different methods (muscular - skeletal modeling vs muscular - skeletal modeling? Wait, no, Cost et al. and Bates/Falkingham: Cost et al. (2015) and Bates/Falkingham (2012). The methods are similar? But the estimates: Cost et al. 15k - 63k, Bates/Falkingham 35k - 57k. The option says "both groups of researchers used the same method", but Cost et al. and Bates/Falkingham: Cost et al. (2015) method is muscular and skeletal modeling, Bates/Falkingham (2012) is also muscular and skeletal modeling? Wait, no, the table says Meers (2002) is body mass scaling, Gignac/Erickson (2017) is tooth - bone interaction analysis, Cost et al. (2015) is muscular and skeletal modeling, Bates/Falkingham (2012) is muscular and skeletal modeling. But the estimates: Cost et al. 15k - 63k, Bates/Falkingham 35k - 57k. The option says "the estimated maximum bite force produced by Cost et al. exceeded the estimated maximum produced by Bates and Falkingham", but 63k (Cost's max) vs 57k (Bates' max) – 63k is more than 57k. But the option also says "both groups of researchers used the same method to generate their estimates". But the key is the first part: does the data support that Cost's max exceeded Bates'? Yes, 63k > 57k. But wait, let's re - check Option B. Gignac and Erickson (2017) had 8,000–34,000, which is correct as per the table. Wait, maybe I made a mistake. Let's re - examine the table:

Study	Year	Estimation Method	Approximate Bite Force (newtons)
Gignac and Erickson	2017	tooth - bone interaction analysis	8,000–34,000
Meers	2002	body mass scaling	181,000–233,000
Bates and Falkingham	2012	muscular and skeletal modeling	35,000–57,000

Now, Option B: "In their study, Gignac and Erickson used tooth - bone interaction analysis to produce an estimated bite force range with a minimum of 8,000 newtons and a maximum of 34,000 newtons." This matches the table data for Gignac and Erickson. So Option B is correct.

Answer:

B. In their study, Gignac and Erickson used tooth - bone interaction analysis to produce an estimated bite force range with a minimum of 8,000 newtons and a maximum of 34,000 newtons.
