“Cites per paper” is a two-year cited-by rate computed from OpenAlex. It is not a Clarivate Journal Impact Factor — we neither compute nor license that metric (how the two differ). Citation rates differ enormously between fields, so compare within a discipline. What the other figures mean: journal quartile, SJR, h-index and article processing charge.

Scimago Journal Rank 2025
In the Scimago Journal Rank 2025 edition, Acta Palaeontologica Polonica is Q2 in Paleontology (#33 of 125 journals).

OpenAlex counts about 20.2 citations per paper over two years; Scopus, through Scimago, counts 1.43 per document. The two databases index different journals, documents and citations, so the figures differ. Neither is a Clarivate Journal Impact Factor.
The quartile is the one Scimago prints for each category. Rank is the journal's position by SJR among the journals Scimago lists in that category (#1 is the highest); “—” means we hold no rank consistent with that quartile. The document count is what Scopus indexed that year, which can be lower than a journal's full output. Source: SCImago Journal Rank 2025 edition, from Scopus data (scimagojr.com, CC BY-NC).
Acta Palaeontologica Polonica is Q2 in Paleontology (2025 edition, #33 of 125 journals), with SJR 0.618 (Scimago) and an h-index of 62 (OpenAlex). Listed in DOAJ, Scopus, Web of Science.

Frequently asked
Is Acta Palaeontologica Polonica a predatory journal?
Our screening does not flag Acta Palaeontologica Polonica. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in DOAJ, Scopus, Web of Science, which is a positive signal.
Is Acta Palaeontologica Polonica indexed in Scopus or Web of Science?
Per our venue index, Acta Palaeontologica Polonica appears in: DOAJ, Scopus, Web of Science. Index membership changes over time — confirm on the index's own site before relying on it.
What is the impact factor of Acta Palaeontologica Polonica?
Papers in Acta Palaeontologica Polonica are cited about 20.2 times each within two years of publication, and Scimago places it in Q2, with an h-index of 62. Those are the open equivalents: the Clarivate Journal Impact Factor is a proprietary metric we neither compute nor license, so we show the two-year citation rate and Scimago quartile instead — they answer the same question of how heavily the journal is cited. A citation rate is a property of a field as much as of a journal.
What Scimago quartile is Acta Palaeontologica Polonica (Q1, Q2, Q3, or Q4)?
In the Scimago Journal Rank 2025 edition, Acta Palaeontologica Polonica is Q2 in Paleontology (#33 of 125 journals). Quartiles split the journals in a subject category into four equal groups by SJR, so Q1 is the most-cited quarter and Q4 the least; Acta Palaeontologica Polonica is cited about 20.2 times per paper over two years, with an h-index of 62.
What is the Web of Science (JCR) quartile of Acta Palaeontologica Polonica?
The Web of Science quartile comes from Clarivate's Journal Citation Reports (JCR), a proprietary product we neither license nor compute — so we cannot state a JCR quartile for Acta Palaeontologica Polonica. The open equivalent is its Scimago quartile, Q2, derived from Scopus citation data. Because JCR ranks against Web of Science and Scimago against Scopus, the two can differ, so check Clarivate's site directly if you need the JCR quartile specifically.
Is Acta Palaeontologica Polonica open access?
Our index records its access status as "gold". Where this is derived from publisher-level signals rather than works-level data it is a heuristic, so confirm on the journal's own site — particularly if an article processing charge matters to you.
What is the article processing charge (APC) to publish in Acta Palaeontologica Polonica?
Article processing charge (APC): €22 per accepted article (DOAJ). Fee waivers are available. The exact charge can vary by article type and any fee waiver, so confirm the current amount on the journal's own site.
How long does Acta Palaeontologica Polonica take to publish a paper?
Submission to publication for Acta Palaeontologica Polonica takes about ~16 wk — DOAJ self-reported. Treat it as indicative rather than a guarantee: editorial times vary by article type, reviewer availability and season, and a self-reported figure is the journal's own. We do not hold a peer-review acceptance rate for Acta Palaeontologica Polonica.
